Trait CheckedSquareRoot 

pub trait CheckedSquareRoot: Sized {
    type Output;

    // Required methods
    fn checked_sqrt(&self) -> CtOption<Self::Output>;
    fn checked_sqrt_vartime(&self) -> Option<Self::Output>;
}

Support for calculating checked square roots.

Required Associated Types

type Output

Output of the square root operation.

Required Methods

fn checked_sqrt(&self) -> CtOption<Self::Output>

Computes sqrt(self), returning none if no root exists.

fn checked_sqrt_vartime(&self) -> Option<Self::Output>

Computes sqrt(self), returning none if no root exists.

Variable time with respect to 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.
