Provided Methods§
Sourcefn ceil_divmod(self, y: Self) -> (Self, i32)
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.
Sourcefn ceil_div(self, y: Self) -> Self
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.
Sourcefn ceil_mod(self, y: Self) -> i32
fn ceil_mod(self, y: Self) -> i32
Get the fast ceiling modulus from integer division. Not safe, since the remainder can easily overflow.
Sourcefn bit_length(self) -> u32
fn bit_length(self) -> u32
Get the number of bits in a value.
Sourcefn overflow_digits(radix: u32) -> usize
fn overflow_digits(radix: u32) -> usize
Get the maximum number of digits before the slice will overflow.
This is effectively the floor(log(2**BITS-1, radix)), but we can try to go a bit lower without worrying too much.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
