rustlang – Arunmozhi

Dev notes from learning Rust.

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.
