Trait BumpAllocatorArena 

pub trait BumpAllocatorArena {
    // Required methods
    fn start(&self) -> *const u8;
    fn size(&self) -> usize;
    fn ensure_min_size(
        &self,
        min_size: usize,
    ) -> BumpAllocatorArenaResult<usize>;

    // Provided method
    fn past_end(&self, ptr: *const u8) -> Option<usize> { ... }
}

Trait to model a consecutive chunk of linear memory for bump allocators.

Required Methods

fn start(&self) -> *const u8

Returns the first pointer in the arena.

fn size(&self) -> usize

Returns the current size of the arena in bytes.

fn ensure_min_size(&self, min_size: usize) -> BumpAllocatorArenaResult<usize>

Ensures that the arena is at least min_size bytes big, or returns an error if that is not possible.

Provided Methods

fn past_end(&self, ptr: *const u8) -> Option<usize>

Returns the number of bytes ptr is pointing past the end of the arena. Returns None if ptr is not pointing past the end.
