Hire top talented Rust developers with Ultragenius
Rust is a robust and statically-typed language developed for enabling safe concurrency and managing memory efficiently in the program. Rust gives the Rust developers choice of storing data on the heap or on the stack and automatically cleans the memory when it is no longer needed, thus also enables fast memory access. Rust’s static typing encourages long-term code maintainability and requires top-level items such as constant and function arguments to be of explicit types and allows type inference inside the function.

Want to hire Remote Rust developers on your own? Here are the skills you must look for while hiring a Rust developer
Hiring Rust developers might be a complicated task for you if you are a non-technical manager. Rust is a statically typed robust programming language designed for ensuring safe concurrency and efficient memory management by using the borrow checker to authenticate references. Rust is very similar to C++ but provides better performance and high memory utilization as compared to C++. Rust is listed in the demanding language of 2021. But, hiring the Rust developers among thousands of Rust developers is a challenging task for anyone even when one is an expertise in technical field. So, Ultragenius is here to assist you while hiring the top talented developers on your own.
The following skills you must ensure while hiring a Rust developer –
Ability to write effective and efficient code in Rust
The Rust developer you are hiring must be able to write clean, concise and pragmatic code in Rust. Rust includes a vast set of libraries called collections that contains various data structures and algorithms. Rust also provides an excellent support for functional data structures. The developer must know about scalar and compound data types.
Knowledge of Rust data types
Rust supports two categories of data types – scalar data types and compound data types.
A scalar data type is a single value datatype. Scalar data types are integers, floating point numbers, characters, and booleans.
A compound data type groups multiple values of same or different types into one single presentation. Compound data types has sub-categories as – arrays and tuples. Arrays stores homogeneous elements of fixed size and cannot be grown or shrunked. Tuples stores elements of different data types but has fixed size.
Firm understanding of Collections
Rust has enriched library which provides a vast set of data structures and algorithms called collections. These collections can be grouped into four main categories :
- Sequences : LinkedList, Vec, VecDeque.
- Maps : BTreeMap, HashMap.
- Sets : BTreeSet, HashSet.
- Miscellaneous : BinaryHeap.
Ability to organize code in modules and knowledge of crate
Rust programming language provides a robust module system which helps Rust developers split the code hierarchically in the form of logical units called modules and manage code visibility (keeping it public or private). A module can be a group of functions, traits, structs, impl blocks, etc.
A crate is a unit of compilation in Rust. Crates are globally installed for a user in /. cargo/registry. Whenever rust file_name.rs is called, file_name.rs is treated as a crate file. By default, the rustc command produces a binary file from crate. The default behavior can be overridden by passing the command –crate-type flag to lib.
Experienced working with code versioning tools like Git, SVN, TFS
Top Rust developers requires very strong knowledge of version control systems, like Git, SVN, TFS and Mercurial. Mostly they use the Git system with their work because it helps them collaborate and organize code as well as maintain changes that occur in it. It also helps review old codes and compare them to newly updated versions – pulls from a repository or manages commit histories by doing add, push, pulls, commits. Rust developers must know how to do branching temporarily for different work fields so people can work independently on their own version of the code without interfering with others’ projects.
Understanding of Object Oriented Programming
Object Oriented Programming is a widely used paradigm for solving project domain problems. The four pillars of OOP are Encapsulation, Inheritance, Abstraction, and Polymorphism.
Encapsulation – Encapsulation bundles the data along with member functions that operate on the data. It binds the data into a single unit.
Inheritance – Inheritance is the mechanism by which a class can extend the functionality of another class. Inheritance gives the Rust developer an advantage to reuse the same code.
Abstraction – Abstraction enables data-hiding by showing the user only the necessary details and hiding the implementation details. Polymorphism is the ability of a function to take many forms.
Polymorphism – Polymorphism is of two types – Compile-time Polymorphism and Run-time Polymorphism. In Compile-time Polymorphism, the invoking method is decided by the type or number of arguments if there are multiple methods present with the same name. Run-time Polymorphism is achieved through Method Overriding. The child class provides the specific implementation of the parent class and the method invoked is decided at the run-time.
Knowledge of Memory Management in Rust
Rust provide efficient memory utilization as there is manual memory management where the Rust developer has explicit control over allocating and de-allocating memory in programs. Rust is designed as a memory-safe language. It inhibits usage of dangling pointers, null pointers, race conditions, etc. The values are initialized only through a fixed set of rules, which need values to be already initialized. The Rust developers must know about memory leaks and its causes and that creating a cycle of shared references result in memory leak.
Understanding of HTTP and TCP Protocols
The Rust developer have to modify an existing HTTP server and put an SSL layer over it, design a non-asynchronous echo server over TCP, and test web and HTTP sockets in Rust. The Rust developer must know about HTTP (Hyper Text Transfer Protocol) and TCP (Transaction Control Protocol). HTTP provides the users a way for interacting with web resources by transferring hypermedia documents, for example, HTML files between a web client and a server. Transaction Control Protocol (TCP) is designed to send information packets over the network and ensures successful data transmission without compromising information.
Firm understanding of dependency management with Cargo
Cargo is the package manager in Rust. It downloads the necessary dependencies in Rust development, creates distributed packages, and uploads the packages to the crates.io, the package registry of Rust’s community. Cargo has detailed documentation and can be easily accessed.
Knowledge of immutability and traits
Immutable objects are the ones whose state cannot be altered once it is created. Rust provides the concept of Traits for implementing run-time polymorphism. Calling a function at run-time on a trait object generates virtual dispatch. Each instance of a pointer to a trait object includes – an instance pointer to a T type that implements a kind of trait, a virtual method table (also called vtable) which has for each method of a trait and its super-traits that T trait implements, and a function pointer to the implementation of type T.
Familiarity with WebSocket library in Rust
The WebSocket is a protocol used for enabling web browser and web server interaction with a lower overhead. Rust provides a WebSocket library to implement web sockets in the program. Web Sockets provide a full-duplex communication channels over a single Transaction Control Protocol (TCP) connection. The Rust developers must know how WebSocket library works in Rust. The library offers a secure message level API implementation, an API for data frames, and has the ability to customize and extend behavior.
Problem-Solving Mindset with strong communication skills
The Top Rust developer must have a strong problem solving skill because it helps developers to utilize existing solutions for the projects more efficiently, thinking abstractly, and enables them to write pseudocode for their project. The developer must know how to debug the code as well. Also, check if the Rust developer is able to write clean and concise code and can fluently communicate with other team members while explaining the code.

Top Interview Questions to ask while hiring a Rust developer
The key features of Rust are -
- Memory-Safety - One of the core features of Rust is providing memory safe environment to the developer.
- Ownership - Rust has a unique ownership system where the value's scope is same as the owner's scope.
- Clippy - Clippy is a collection of lints that catches common mistakes to improve the code quality.
- Cargo - Cargo is the package manager in Rust. It downloads the necessary dependencies in Rust development, creates distributed packages, and uploads the packages to crates.io.
- RLS - RLS stands for Rust Language Server. The RLS provides a server which runs in the background, a standard interface for IDEs, editors and tools.
- Rustfmt - Rustfmt is a tool for code formatting in Rust.
- Immutable Types and Traits - Rust provides the concept of immutable data types and traits concept which tells compiler about the functionality of a particular type which can be shared with other data types also.
RLS stands for Rust Language Server. It provides a background server to run the Rust applications. RLS provides an interface for IDEs, editors, and several other tools with information about programs. Rust offers freelance Rust developers with the core functionalities like 'goto' defintion, automatic code completion, reformatting, symbol search, enabling code renaming and refactoring, etc.
A trait tells the compiler about the functionality of a particular type. Traits define shared behavior in an abstract way and are used to specify that a generic type can be any type which possesses certain behavior. Traits provides the abstract definition of the shared behavior among various types. Same behavior is shared by the different types if you invoke the same methods on all those types.
Rust compiler uses lifetimes to keep track for how much time references are valid. Checking the references is one of the core functionalities of borrow checker. Lifetimes enable borrow checkers confirm that there is no invalid reference in the program which helps in utilizing memory efficiently.
Rust provides the derive attribute which permits new items to be generated automatically for data structures. Derive asks the compiler to auto-generate a perfect implementation of the Debug trait.
Derive attribute uses MetaListPaths to specify a traits list and implement paths for deriving macros to the process.
PartialEq stands for partial equality. It defines a relation to be symmetric and transitive. For example, for all a and b for the respective types (a==b -> b==a).
For all a,b,c of respective types (a==b ^ b==c) - >(c==a).
Eq in PartialEq declares all types are reflexive in itself. For example, a==a, for some variable a of some type.
A crate acts as a compilation unit in Rust. Crates are globally installed for a user in /. cargo/registry. Whenever rust file_name.rs is called, file_name.rs is treated as a crate file. By default, the rustc command produces a binary file from crate. The default behavior can be overridden by passing the command --crate-type flag to lib.
The extern keyword is used in conjunction with keyword crate to make the freelance Rust developers aware of the other Rust crates used in the program and also in context of Foreign Function Interfaces (FFI). While the enum keyword represents data associated with one of the possible variants. Each variant can optionally have its associated data.
