Function core::intrinsics::const_allocate

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

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

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

在编译时分配。不应在运行时调用。
