[−][src]Trait fixed::traits::FixedUnsigned

pub trait FixedUnsigned: Fixed {
    fn is_power_of_two(self) -> bool;

    fn next_power_of_two(self) -> Self;

    fn checked_next_power_of_two(self) -> Option<Self>;

    fn unwrapped_next_power_of_two(self) -> Self;
}

This trait provides methods common to all unsigned fixed-point numbers.

Methods common to all fixed-point numbers including signed fixed-point numbers are provided by the Fixed supertrait.

This trait is sealed and cannot be implemented for more types; it is implemented for FixedU8, FixedU16, FixedU32, FixedU64, and FixedU128.

Required methods

fn is_power_of_two(self) -> bool

Returns true if the fixed-point number is 2k for some integer k.

fn next_power_of_two(self) -> Self

Returns the smallest power of two that is ≥ self.

fn checked_next_power_of_two(self) -> Option<Self>

Returns the smallest power of two that is ≥ self, or None if the next power of two is too large to represent.

fn wrapping_next_power_of_two(self) -> Self

Returns the smallest power of two that is ≥ self, wrapping to 0 if the next power of two is too large to represent.

fn unwrapped_next_power_of_two(self) -> Self

Returns the smallest power of two that is ≥ self, panicking if the next power of two is too large to represent.

This method is only available when the unwrapped experimental feature is enabled.

Panics

Panics if the result does not fit.
