Trait Implementations

impl<'a> AcceptVisitor<'a> for ConstraintKind

fn accept(&'a self, visitor: &mut dyn Visitor<'a>)

Walk a visitor over the contents of self.

impl Clone for ConstraintKind

fn clone(&self) -> ConstraintKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintKind

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

Formats the value using the given formatter.

impl<'a> ForEachChild<'a> for ConstraintKind

fn for_each_child(&'a self, each: &mut dyn FnMut(&'a dyn AnyNode<'a>))

Apply a function to each child node.

impl<'a> ForEachNode<'a> for ConstraintKind

fn for_each_node(&'a self, each: &mut dyn FnMut(&'a dyn AnyNode<'a>))

Apply a function to this node.

impl PartialEq for ConstraintKind

fn eq(&self, other: &ConstraintKind) -> 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.

impl<'a> WalkVisitor<'a> for ConstraintKind

fn walk(&'a self, visitor: &mut dyn Visitor<'a>)

Walk a visitor over self.

Calling this function is equivalent to calling:

• visitor.pre_visit_constraint_kind(self)
• self.accept(visitor)
• visitor.post_visit_constraint_kind(self);
