Struct swim_c::stdlib::MallocHeap

pub struct MallocHeap<'a> { /* fields omitted */ }

Block allocator backed by libc malloc.

Methods

impl<'a> MallocHeap<'a>

pub const fn new(unit: usize) -> MallocHeap<'a>

Returns a new Heap that allocates memory blocks with at least unit size bytes using libc malloc.

pub fn global() -> &'a MallocHeap<'a>

Returns a reference to a Heap that allocates memory using libc malloc.

pub fn block_size(&self) -> usize

Returns the minimum number of bytes in each memory block in this MallocHeap.

pub fn live(&self) -> usize

Returns the number of currently allocated memory blocks in this MallocHeap.
