Crate 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};

musli_allocator::with(|alloc| {
    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);
});
