Trait heapless::PowerOfTwo

pub trait PowerOfTwo { }

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::{P4, P8, PowerOfTwo};

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>();

Implementations on Foreign Types

impl<U> PowerOfTwo for PInt<U> where
    U: NonZero + Unsigned + PowerOfTwo, 

impl<U> PowerOfTwo for UInt<U, B0> where
    U: Unsigned + PowerOfTwo, 

impl PowerOfTwo for UInt<UTerm, B1>
