musli-allocator

Allocation support for Müsli.

This crate contains two types of allocators:

• The [System] allocator, which uses the system allocation facilities. Particularly std::alloc::System.
• The [Stack] allocator, which can allocate buffers from a fixed-size slice.

Examples

use musli::{Allocator, Buf};

let mut buf = musli_allocator::buffer();
let alloc = musli_allocator::new(&mut buf);

let mut a = alloc.alloc().expect("allocation a failed");
let mut b = alloc.alloc().expect("allocation b failed");

b.write(b"He11o");
a.write(b.as_slice());

assert_eq!(a.as_slice(), b"He11o");
assert_eq!(a.len(), 5);

a.write(b" W0rld");

assert_eq!(a.as_slice(), b"He11o W0rld");
assert_eq!(a.len(), 11);

let mut c = alloc.alloc().expect("allocation c failed");
c.write(b"!");
a.write(c.as_slice());

assert_eq!(a.as_slice(), b"He11o W0rld!");
assert_eq!(a.len(), 12);
