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
pub use buf::Buf;
