Struct rustc_expand::mbe::macro_parser::MatcherTtFrame

source · [−]

struct MatcherTtFrame<'tt> {
    elts: &'tt [TokenTree],
    idx: usize,
}

Expand description

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

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

Fields

elts: &'tt [TokenTree]

The “parent” matcher that we are descending into.

idx: usize

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
