source · [−]pub struct Group {

}Fields
delimiter: Delimiterstream: TokenStreamspan: DelimSpanflatten: boolA 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).
