BumpAllocator

Struct BumpAllocator 

Source
pub struct BumpAllocator<'a, M: BumpAllocatorArena = &'a [u8], H: Head = SingleThreadedHead> { /* private fields */ }
Expand description

A generic bump allocator.

The bump allocator works on memory M, tracking where the remaining free memory starts using head H.
