}Expand description
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 significant_bits(self) -> u32
fn significant_bits(self) -> u32
Returns the number of bits required to represent the value.
See also
FixedU32::significant_bits.
fn is_power_of_two(self) -> bool
fn is_power_of_two(self) -> bool
Returns true if the fixed-point number is
2k for some integer k.
See also
FixedU32::is_power_of_two.
fn highest_one(self) -> Self
fn highest_one(self) -> Self
Returns the highest one in the binary representation, or zero
if self is zero.
See also FixedU32::highest_one.
fn next_power_of_two(self) -> Self
fn next_power_of_two(self) -> Self
Returns the smallest power of two that is ≥ self.
See also
FixedU32::next_power_of_two.
fn checked_next_power_of_two(self) -> Option<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.
See also
FixedU32::checked_next_power_of_two.
fn wrapping_next_power_of_two(self) -> Self
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.
See also
FixedU32::wrapping_next_power_of_two.
fn unwrapped_next_power_of_two(self) -> Self
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.
See also
FixedU32::unwrapped_next_power_of_two.
