Learning Rust – Day 1

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.
