impl<L: Language> Matcher<L> for Pattern<L>

source

fn match_node_with_env<'tree>(
 &self,
 node: Node<'tree, L>,
 env: &mut MetaVarEnv<'tree, L>
) -> Option<Node<'tree, L>>

Returns the node why the input is matched or None if not matched. The return value is usually input node itself, but it can be different node. For example Has matcher can return the child or descendant node. Read more
