Function alloc::heap::deallocate
[−]
[src]
pub unsafe fn deallocate(ptr: *mut u8, old_size: usize, align: usize)
Unstable (
heap_api #27700): the precise API and guarantees it provides may be tweaked slightly, especially to possibly take into account the types being stored to make room for a future tracing garbage collector
Deallocates the memory referenced by ptr.
The ptr parameter must not be null.
The old_size and align parameters are the parameters that were used to
create the allocation referenced by ptr. The old_size parameter may be
any value in range_inclusive(requested_size, usable_size).
