Trait num_traits::UnsignedInt [−] [src]

pub trait UnsignedInt: Int {
    fn is_power_of_two(self) -> bool;
    fn next_power_of_two(self) -> Self;
    fn checked_next_power_of_two(self) -> Option<Self>;
}

Unsigned integers.

Required Methods

fn is_power_of_two(self) -> bool

Returns true if and only if self == 2^k for some k.

fn next_power_of_two(self) -> Self

Returns the smallest power of two greater than or equal to self. Unspecified behavior on overflow.

fn checked_next_power_of_two(self) -> Option<Self>

Returns the smallest power of two greater than or equal to n. If the next power of two is greater than the type's maximum value, None is returned, otherwise the power of two is wrapped in Some.
