Trait SquareRootField 

pub trait SquareRootField: Field {
    // Required methods
    fn legendre(&self) -> LegendreSymbol;
    fn sqrt(&self) -> Option<Self>;
    fn sqrt_in_place(&mut self) -> Option<&mut Self>;
}

The interface for a field that supports an efficient square-root operation.

Required Methods

fn legendre(&self) -> LegendreSymbol

Returns a LegendreSymbol, which indicates whether this field element is 1 : a quadratic residue 0 : equal to 0 -1 : a quadratic non-residue

fn sqrt(&self) -> Option<Self>

Returns the square root of self, if it exists.

fn sqrt_in_place(&mut self) -> Option<&mut Self>

Sets self to be the square root of self, if it exists.

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.
