enum TokenTreeOrTokenTreeSlice<'tt> {
    Tt(TokenTree),
    TtSeq(&'tt [TokenTree]),

Implementations

source

impl<'tt> TokenTreeOrTokenTreeSlice<'tt>

source

fn len(&self) -> usize

Returns the number of constituent top-level token trees of self (top-level in that it will not recursively descend into subtrees).

source

fn get_tt(&self, index: usize) -> TokenTree

The index-th token tree of self.
