Trait Implementations

impl<'lex> Copy for Token<'lex>

impl<'lex> Clone for Token<'lex>

fn clone(&self) -> Token<'lex>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'lex> Debug for Token<'lex>

fn fmt(&self, __arg_0: &mut Formatter) -> Result
