pub struct AttrAnnotatedTokenStream(pub Lrc<Vec<(AttrAnnotatedTokenTree, Spacing)>>);
Expand description

A AttrAnnotatedTokenStream is similar to a TokenStream, but with extra information about the tokens for attribute targets. This is used during expansion to perform early cfg-expansion, and to process attributes during proc-macro invocations.

Tuple Fields

0: Lrc<Vec<(AttrAnnotatedTokenTree, Spacing)>>

Implementations

Converts this AttrAnnotatedTokenStream to a plain TokenStream During conversion, AttrAnnotatedTokenTree::Attributesget 'flattened' back to aTokenStreamof the formouter_attr attr_target`. If there are inner attributes, they are inserted into the proper place in the attribute target tokens.
