Trait Logarithm

pub trait Logarithm: Sized {
    // Required methods
    fn log2_ceil(self) -> Self;
    fn log2(self) -> Self;
    fn checked_log(self, base: Self) -> Option<Self>;
    fn log(self, base: Self) -> Self;
}

Extension trait adding logarithm methods to integers.

Required Methods

fn log2_ceil(self) -> Self

Returns ceiling(log2(self)).

fn log2(self) -> Self

Returns log2(self).

fn checked_log(self, base: Self) -> Option<Self>

Returns the integer logarithm base base of self, or None if it is not possible to take the log base base of self.

fn log(self, base: Self) -> Self

Returns the integer logarithm base base of self.

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.
