Function libmimalloc_sys::mi_good_size

pub unsafe extern "C" fn mi_good_size(size: usize) -> usize

Return the used allocation size.

Returns the size n that will be allocated, where n >= size.

Generally, mi_usable_size(mi_malloc(size)) == mi_good_size(size). This can be used to reduce internal wasted space when allocating buffers for example.
