Function core::intrinsics::const_deallocate

pub unsafe extern "rust-intrinsic" fn const_deallocate(
    ptr: *mut u8, 
    size: usize, 
    align: usize
)

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

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

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.
• 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.
