Trait integer_sqrt::IntegerSquareRoot

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

    // Provided method
    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) -> Selfwhere 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
