- [API Documentation](http://docs.rs/fixedvec/)
`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
-----------
`fixedvec` is tested against the current stable, beta, and nightly, as well as
the previous two stable Rust releases.
The `#![no_std]` attribute is available in stable Rust, but building _binaries_
without libstd still requires the nightly compiler.
To use `fixedvec`, add the following to your `Cargo.toml`:
```toml
[dependencies]
fixedvec = "*"
```
Then add the following to your crate root:
```rust,ignore
#[macro_use] extern crate fixedvec;
```
Example
-------
Buffering and mutating a list of bytes:
```rust
#[macro_use] extern crate fixedvec;
use fixedvec::FixedVec;
fn main() {
let mut preallocated_space = alloc_stack!([u8; 10]);
let mut vec = FixedVec::new(&mut preallocated_space);
assert_eq!(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]);
}
```
Minimum Supported Rust Version (MSRV)
-------------------------------------
This crate is guaranteed to compile on stable Rust 1.23.0 and up. It *might*
compile with older versions but that may change in any new patch release.
