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

Deallocates a memory which allocated by intrinsics::const_allocate at compile time. At runtime, does nothing.


  • 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.
  • If the ptr is created in an another const, this intrinsic doesn’t deallocate it.
  • If the ptr is pointing to a local variable, this intrinsic doesn’t deallocate it.
