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

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

🔬 This is a nightly-only experimental API. (`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.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
