Trait integer_sqrt::IntegerSquareRoot

pub trait IntegerSquareRoot {
    fn integer_sqrt_checked(&self) -> Option<Self>
    where
        Self: Sized;

    fn integer_sqrt(&self) -> Self
    where
        Self: Sized,
    { ... }
}

A trait implementing integer square root.

Required Methods

fn integer_sqrt_checked(&self) -> Option<Self> where
    Self: Sized, 

Find the integer square root, returning None if the number is negative (this can never happen for unsigned types).

Provided Methods

fn integer_sqrt(&self) -> Self where
    Self: Sized, 

Find the integer square root.

See Integer_square_root on wikipedia for more information (and also the source of this algorithm)

Panics

For negative numbers (i family) this function will panic on negative input
