Trait Implementations

impl Clone for EmptyContext

fn clone(&self) -> EmptyContext

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

Performs copy-assignment from source.

impl Debug for EmptyContext

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

Formats the value using the given formatter.

impl Default for EmptyContext

fn default() -> EmptyContext

impl PartialEq for EmptyContext

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

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

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