[![Build Status](https://travis-ci.com/slightlyoutofphase/staticvec.svg?branch=master)](https://travis-ci.com/slightlyoutofphase/staticvec)
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:
```rust
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);
}
}
}
```
