Module rustc_parse::parser::attr_wrapper

Modules

Structs

AttrWrapper

A wrapper type to ensure that the parser handles outer attributes correctly. When we parse outer attributes, we need to ensure that we capture tokens for the attribute target. This allows us to perform cfg-expansion on a token stream before we invoke a derive proc-macro.

LazyAttrTokenStreamImpl 🔒

Functions

has_cfg_or_cfg_attr 🔒

Returns true if attrs contains a cfg or cfg_attr attribute

make_token_stream 🔒

Converts a flattened iterator of tokens (including open and close delimiter tokens) into a TokenStream, creating a TokenTree::Delimited for each matching pair of open and close delims.
