Trait Implementations

impl Clone for ExpectedToken

fn clone(&self) -> ExpectedToken

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExpectedToken

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

fn eq(&self, other: &ExpectedToken) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
