AttrTokenStream in rustc_ast::tokenstream - Rust (original) (raw)
Struct AttrTokenStream
pub struct AttrTokenStream(pub Arc<Vec<AttrTokenTree>>);Expand description
An AttrTokenStream 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.
Converts this AttrTokenStream to a plain Vec<TokenTree>. During conversion, any AttrTokenTree::AttrsTarget gets “flattened” back to aTokenStream, as described in the comment onattrs_and_tokens_to_token_trees.
