Trait Implementations

impl<L: Clone, V: Clone> Clone for Ast<L, V>

fn clone(&self) -> Ast<L, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Debug, V: Debug> Debug for Ast<L, V>

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

Formats the value using the given formatter.

impl<L, V: Eq + Hash> FreeVars<Var<V>> for Ast<L, V>

fn free_vars_into<'a>(&'a self, set: &mut HashSet<&'a Var<V>>)

fn free_vars(&self) -> HashSet<&V>

impl<L, V> From<Term<L, V>> for Ast<L, V>

fn from(term: Term<L, V>) -> Self

Converts to this type from the input type.

impl<L, V> From<Var<V>> for Ast<L, V>

fn from(var: Var<V>) -> Self

Converts to this type from the input type.

impl<L: Eq + Hash, V: Eq + Hash> PartialEq for Ast<L, V>

fn eq(&self, rhs: &Self) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn try_from(ast: Ast<L, V>) -> Result<Self, Self::Error>

Performs the conversion.
