Trait Implementations

impl<'a> Clone for Substitution<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Eq for Substitution<'a>

fn assert_receiver_is_total_eq(&self)

impl<'a> PartialEq for Substitution<'a>

fn eq(&self, other: &Substitution<'a>) -> bool

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

fn ne(&self, other: &Substitution<'a>) -> bool

This method tests for !=.

impl<'a> Debug for Substitution<'a>

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