Function const_allocate

pub const unsafe fn const_allocate(_size: usize, _align: usize) -> *mut u8

🔬This is a nightly-only experimental API. (core_intrinsics)

Allocates a block of memory at compile time. At runtime, just returns a null pointer.

Safety

• The align argument must be a power of two.
  • At compile time, a compile error occurs if this constraint is violated.
  • At runtime, it is not checked.
