Crate polymock

A fast thread-safe bump allocation arena.

polymock provides a fast allocation Arena using the bump allocation strategy. It’s primary use case is high-throughput multi-threaded network applications which allocate and free buffers very frequently and cannot afford going through the global allocator.

polymock only supports allocating [u8] buffers. It will never support allocating of different objects.

Using bytes

polymock provides it’s own Bytes type that is a mostly drop-in replacement for the equivalent type from the bytes crate.

Once the construction using a custom vtable will be public, Bytes will be deprecated in favor of the bytes crate.

no_std support

polymock supports no_std, but requires the alloc crate. To enable no_std support disable the default “std” feature:

polymock = { version = "0.2.0", default-features = false }

Example

use polymock::Arena;

let mut arena = Arena::default();

let mut buf = arena.alloc(1500);

for b in buf.iter_mut() {
    *b = 1;
}

let buf1 = buf.freeze();
let buf2 = buf1.clone();

assert_eq!(buf1, buf2);

Re-exports
