Trait Implementations

impl<'a> Copy for Piece<'a>

impl<'a> Clone for Piece<'a>

fn clone(&self) -> Piece<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> PartialEq for Piece<'a>

fn eq(&self, __arg_0: &Piece<'a>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Piece<'a>) -> bool

This method tests for !=.
