fixedvec

![Build Status] (https://img.shields.io/travis/rust-embedded/fixedvec-rs.svg)

API Documentation

fixedvec is a Rust library/crate providing a heapless version of the Rust vector type. Although more limited than the libstd version, fixedvec provides a much-needed "managed" array type for embedded systems or other projects that cannot rely on the heap.

Install/Use

You must be using the nightly Rust release to use fixedvec, as it relies on the unstable libcore feature. If you're building for an embedded system, you're probably on the nightly anyway though.

To use fixedvec, add the following to your Cargo.toml:

toml [dependencies] fixedvec = "*"

Then add the following to your crate root:

```rust

[macro_use] extern crate fixedvec;

```

Example

Buffering and mutating a list of bytes:

```rust

![feature(core)]

extern crate core;

[macro_use] extern crate fixedvec;

use fixedvec::FixedVec;

fn main() { let mut preallocatedspace = allocstack!([u8; 10]); let mut vec = FixedVec::new(&mut preallocatedspace); asserteq!(vec.len(), 0);

vec.push_all(&[1, 2, 3]).unwrap();
assert_eq!(vec.len(), 3);
assert_eq!(vec.as_slice(), &[1, 2, 3]);

vec.map_in_place(|x: &mut u8| { *x *= 2 });
assert_eq!(vec.as_slice(), &[2, 4, 6]);

} ```
