Module rustc_parse::parser::attr_wrapper
source · [−]Structs
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.
Functions
Returns
true if attrs contains a cfg or cfg_attr attributeConverts 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.
