Struct rustc_expand::mbe::macro_parser::MatcherTtFrame[−][src]

struct MatcherTtFrame<'tt> {
    elts: TokenTreeOrTokenTreeSlice<'tt>,
    idx: usize,
}
Expand description

An unzipping of TokenTrees… see the stack field of MatcherPos.

This is used by inner_parse_loop to keep track of delimited submatchers that we have descended into.

Fields

elts: TokenTreeOrTokenTreeSlice<'tt>
Expand description

The “parent” matcher that we are descending into.

idx: usize
Expand description

The position of the “dot” in elts at the time we descended.
