Implementations

impl<'a> Cursor<'a>

pub fn eof(self) -> bool

Check whether it is eof

pub fn end(self) -> Option<&'a Subtree>

If the cursor is pointing at the end of a subtree, returns the parent subtree

pub fn subtree(self) -> Option<Cursor<'a>>

If the cursor is pointing at a Subtree, returns a cursor into that subtree

pub fn token_tree(self) -> Option<TokenTreeRef<'a>>

If the cursor is pointing at a TokenTree, returns it

pub fn bump(self) -> Cursor<'a>

Bump the cursor

pub fn bump_subtree(self) -> Cursor<'a>

Bump the cursor, if it is a subtree, returns a cursor into that subtree

pub fn is_root(&self) -> bool

Check whether it is a top level

Trait Implementations

impl<'a> Clone for Cursor<'a>

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

Returns a copy of the value.

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