Enum rustc_const_math::ConstUsize

pub enum ConstUsize {
    Us16(u16),
    Us32(u32),
    Us64(u64),
}

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

Depending on the target only one variant is ever used in a compilation. Anything else is an error. This invariant is checked at several locations
