polymock

A thread-safe bump allocation arena for bytes.

polymock is primarly targeted at high-throughput multi-threaded network applications which need to allocate and free buffers very frequently and cannot afford going through the global allocator.

Usage

Add polymock to your Cargo.toml:

polymock = "0.2.0"

Next create an allocation arena and allocate some buffers:

use polymock::Arena;

// Create a bump arena with a chunk size of 1000 bytes.
let arena = Arena::new(1000);

let mut buffers = Vec::new();
for _ in 0..10 {
    // All 10 buffers will be allocated in the same chunk.
    let buf = arena.alloc();

    buffers.push(buf);
}

// The allocated buffers may outlive the arena they
// were allocated with.

drop(arena);

buffers[0][0] = 1;
