Learning Rust - Day 1

Posted on | In

Dev notes from learning Rust.

Official Website: https://www.rust-lang.org

  • Installed the tool from the official website https://www.rust-lang.org/tools/install
  • Started learning from the official Rust Book - https://doc.rust-lang.org/book/
  • Completed the Chapter 1 and learnt about the 2 methods of compilation - using the direct rustc compiler and the cargo package manager

Notes

  • Rust is a compiled language - different from my daily drivers Python and JavaScript both interpreted languages.
  • Compiled means re-learning the difference between passing by reference and passing by value
  • Rust has mutability at the core of data management - so being conscious about immutable and mutable data
  • Errors are handled as a part of the Result of functions. Doesn’t need an explicit try...except (at least at this point)
  • Packages are called crates and there are binary crates & library crates
  • https://crates.io/ is the package registry
  • Cargo.lock file acts as the record of dependencies for Reproducible builds
  • cargo update updates the packages to the most recent bugfix version
  • there is something called Traits which provide access to functions of a crate.
