# Function std::alloc::dealloc

    pub unsafe fn dealloc(ptr: *mut u8, layout: Layout)

Expand description

Deallocate memory with the global allocator.

This function forwards calls to the `GlobalAlloc::dealloc` method of the allocator registered with the `#[global_allocator]` attribute if there is one, or the `std` crate’s default.

This function is expected to be deprecated in favor of the `dealloc` method of the `Global` type when it and the `Allocator` trait become stable.

## Safety

See `GlobalAlloc::dealloc`.
