Struct rustc_expand::proc_macro_server::Group

pub struct Group {
    delimiter: Delimiter,
    stream: TokenStream,
    span: DelimSpan,
    flatten: bool,
}

Fields

delimiter: Delimiter

stream: TokenStream

span: DelimSpan

flatten: bool

A hack used to pass AST fragments to attribute and derive macros as a single nonterminal token instead of a token stream. FIXME: It needs to be removed, but there are some compatibility issues (see #73345).

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.
