lessvec

A minimal, educational Vec-like collection implemented with only the Rust standard library.

Quick example

use lessvec::LessVec;

let mut v = LessVec::new();
v.push(1);
v.push(2);
assert_eq!(v.as_slice(), &[1, 2]);

Prelude & macro

lessvec exposes a small prelude with the LessVec type and the lessvec! macro:

use lessvec::prelude::*;

// macro to construct a LessVec (same syntax as std `vec!`)
let v = lessvec![1, 2, 3];
assert_eq!(v.as_slice(), &[1, 2, 3]);

// repeating element form (requires Clone)
let r = lessvec![5; 4];
assert_eq!(r.as_slice(), &[5, 5, 5, 5]);

You can also import the macro directly if you prefer:

use lessvec::lessvec;
let v = lessvec![1, 2, 3];
