Overview

Tools

As we've just seen, Rust includes some great tooling. Things like cargo and rustup make it a real pleasure to use. And we'll see more as we go.

Rust	Perl
`rustc`	`perl`
`cargo`	`cpanm`, `dzil`, and more
`rustup`	`plenv`, `perlbrew`
`rustfmt`	`perltidy`
`clippy`	`perlcritic`
`rustdoc`	`perldoc`
module	module
crate	distribution
crates.io	metacpan.org
Rust Foundation	The Perl Foundation

We've spent decades coming up with some of this stuff in Perl. In Rust, it's all here already!

Differences

As we'll see, there are a lot of huge differences between Perl and Rust.

Rust	Perl
static types	dynamic types
strong types	weak types
move, borrow	copy, reference
immutable by default (`mut`)	mutable
private by default (`pub`)	public
expressions	statements, expressions

Similarities

But some things will be familiar. Scope works pretty much the same. Both languages use the use keyword and :: in similar ways. And both have lots of "C-like" syntax in common.
