Function alloc::heap::allocate [] [src]

pub unsafe fn allocate(size: usize, align: usize) -> *mut u8
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

Return a pointer to size bytes of memory aligned to align.

On failure, return a null pointer.

Behavior is undefined if the requested size is 0 or the alignment is not a power of 2. The alignment must be no larger than the largest supported page size on the platform.
