Provided Methods§

fn ceil_divmod(self, y: Self) -> (Self, i32)

Get the fast ceiling of the quotient from integer division. Not safe, since the remainder can easily overflow.

fn ceil_div(self, y: Self) -> Self

Get the fast ceiling of the quotient from integer division. Not safe, since the remainder can easily overflow.

fn ceil_mod(self, y: Self) -> i32

Get the fast ceiling modulus from integer division. Not safe, since the remainder can easily overflow.

fn bit_length(self) -> u32

Get the number of bits in a value.

fn is_odd(self) -> bool

Returns true if the least-significant bit is odd.

fn is_even(self) -> bool

Returns true if the least-significant bit is even.

Object Safety§

This trait is not object safe.
