Introduction to Rust

Rust is a fast, safe, and concurrent systems programming language that is quickly gaining popularity for writing HFT applications

Rust lang

High frequency trading (HFT) applications require extremely low latencies and high performance to ensure that trades are executed quickly and accurately. As a result, choosing the correct programming language is crucial for the success of an HFT system.

One language that is well-suited for HFT applications is Rust. Rust is a systems programming language that was designed to be fast, safe, and concurrent. In addition, it has a unique ownership and borrowing system that allows for efficient memory management without needing a garbage collector, which can reduce latencies and improve performance.

In addition to its performance benefits, Rust offers strong safety guarantees that can help prevent errors and reduce the risk of financial losses. Its macro system and rich standard library also make it a versatile language that can be used to build a wide range of applications.

Quick setup

  • Install rust
  • Check version: rustc --version
  • To show active/installed toolchains rustup show
  • To update rust run
    rustup update nightly
  • To update rust stable toolchain run To change the default toolchain rustup default nightly`
  • To install specific nightly toolchains rustup toolchain install nightly-2021-08-20
  • Update dependencies in a package cargo update

Useful dev packages

To install globally via cargo install <package>

  • cargo-edit to add cargo-add, cargo-rm, cargo-upgrade commands
  • cargo-watch to watch for changes and reload during development
  • cargo-outdated to check for outdated packages. Once installed, simply
    cargo outdated
  • cargo-expand for macro expansion.
