Trait Implementations

impl<'a> Clone for GroupRule<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for GroupRule<'a>

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

Formats the value using the given formatter.

impl Display for GroupRule<'_>

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

Formats the value using the given formatter.

impl<'a, 'b: 'a> Parent<'a, 'b, GroupRule<'a>> for GenericParams<'a>

fn parent( &'a self, parent_visitor: &'b ParentVisitor<'a, 'b>, ) -> Option<&'a GroupRule<'a>>

Returns the parent for the AST type

impl<'a, 'b: 'a> Parent<'a, 'b, GroupRule<'a>> for GroupEntry<'a>

fn parent( &'a self, parent_visitor: &'b ParentVisitor<'a, 'b>, ) -> Option<&'a GroupRule<'a>>

Returns the parent for the AST type

impl<'a, 'b: 'a> Parent<'a, 'b, GroupRule<'a>> for Identifier<'a>

fn parent( &'a self, parent_visitor: &'b ParentVisitor<'a, 'b>, ) -> Option<&'a GroupRule<'a>>

Returns the parent for the AST type

impl<'a, 'b: 'a> Parent<'a, 'b, Rule<'a>> for GroupRule<'a>

fn parent( &'a self, parent_visitor: &'b ParentVisitor<'a, 'b>, ) -> Option<&'a Rule<'a>>

Returns the parent for the AST type

impl<'a> PartialEq for GroupRule<'a>

fn eq(&self, other: &GroupRule<'a>) -> 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.
