Function std::intrinsics::const_allocate

source · 
pub const unsafe fn const_allocate(_size: usize, _align: usize) -> *mut u8
🔬This is a nightly-only experimental API. (core_intrinsics)
Expand description

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.
