Trait typenum::marker_traits::PowerOfTwo [−][src]
The marker trait for type-level numbers which are a power of two.
This trait should not be implemented for anything outside this crate.
Examples
Here’s a working example:
use typenum::{PowerOfTwo, P4, P8}; fn only_p2<P: PowerOfTwo>() {} only_p2::<P4>(); only_p2::<P8>();
Numbers which are not a power of two will fail to compile in this example:
ⓘ
use typenum::{P9, P511, P1023, PowerOfTwo}; fn only_p2<P: PowerOfTwo>() { } only_p2::<P9>(); only_p2::<P511>(); only_p2::<P1023>();
