[−][src]Enum rustc_expand::mbe::macro_parser::TokenTreeOrTokenTreeSlice

pub(in mbe::macro_parser) enum TokenTreeOrTokenTreeSlice<'tt> {
    Tt(TokenTree),
    TtSeq(&'tt [TokenTree]),
}

Either a sequence of token trees or a single one. This is used as the representation of the sequence of tokens that make up a matcher.

Variants

Tt(TokenTree)
TtSeq(&'tt [TokenTree])

Implementations

impl<'tt> TokenTreeOrTokenTreeSlice<'tt>[src]

pub(in mbe::macro_parser) fn len(
    &self
) -> usize[src]

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

pub(in mbe::macro_parser) fn get_tt(
    &self,
    index: usize
) -> TokenTree[src]

The index-th token tree of self.
