staticvec: A Rust repository from batisteo

Implements a fixed-capacity stack-allocated Vec alternative backed by an array, using const generics.

Note: the word "static" here is meant by the traditional definition of "unchanging" / "not dynamic" etc.

This crate does not use literal static variables for anything.

Fully #![no_std] compatible (with almost no loss of functionality) by setting default-features = false for the staticvec dependency in your Cargo.toml.

Optional support for serialization and deserialization of the StaticVec struct via serde is available by activating the serde_support feature.

Contributions/suggestions/etc. very welcome!

Minimum supported Rust version: due to the use of const generics, this is a nightly-only crate at the moment.

A basic usage example:

use staticvec::*;

fn main() {
  let mut v = StaticVec::<usize, 64>::new();
  for i in 0..v.capacity() {
    v.push(i);
  }
  for i in &v {
    println!("{}", i);
  }
  v.clear();
  v.insert(0, 47);
  v.insert(1, 48);
  v.insert(2, 49);
  v.insert(v.len() - 1, 50);
  v.insert(v.len() - 2, 51);
  v.insert(v.len() - 3, 52);
  for i in &v {
    println!("{}", i);
  }
  for i in &v.reversed().drain(2..4) {
    println!("{}", i);
  }
  while v.is_not_empty() {
    println!("{}", v.remove(0));
  }
  for f in staticvec![12.0, 14.0, 15.0, 16.0].iter().skip(2) {
    println!("{}", f);
  }
  for v in staticvec![
    staticvec![14, 12].sorted(),
    staticvec![18, 16].sorted(),
    staticvec![22, 20].sorted(),
    staticvec![26, 24].sorted(),
  ]
  .iter()
  .cloned::<StaticVec<usize, 2>>()
  {
    for i in &v {
      println!("{}", i);
    }
  }
}
