planck-noalloc

Stack-allocated, no_std collections for Rust.

Provides fixed-size alternatives to heap-allocated data structures, useful in embedded systems, kernels, interrupt handlers, or anywhere heap allocation is unavailable.

Collections

• ArrayVec<T, N> — Fixed-capacity vector backed by a stack array
• RingBuf<T, N> — Fixed-capacity circular buffer for FIFO operations

Usage

[dependencies]
planck-noalloc = "0.1"

use planck_noalloc::vec::ArrayVec;

let mut vec = ArrayVec::<i32, 5>::new();
vec.push(1);
vec.push(2);
assert_eq!(vec.len(), 2);

use planck_noalloc::ringbuf::RingBuf;

let mut buf = RingBuf::<u8, 8>::new();
buf.push(1);
buf.push(2);
assert_eq!(buf.pop(), Some(1));

Features

To use in a no_std environment:

[dependencies]
planck-noalloc = { version = "0.1", default-features = false }
