This crate provides a fast, single-threaded bump allocator for use in performance sensitive contexts.
It can be used for quick and dirty allocation in a loop, where you know memory can be reclaimed all at once at the end.
#![feature(allocator_api)]
use dodgems::BumpCar;
let mut bumpcar = BumpCar::new(1024).unwrap(); // 1kB capacity
for i in 0..100 {
// allocate with the allocator api
let mut v = Vec::new_in(&bumpcar);
v.push(42);
// small fast allocations in hot loop
drop(v);
// reset the capacity once every allocation has been dropped
bumpcar.reset();
}
drop(bumpcar)
Until the allocator_api
is stable, this crate requires nightly.
