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.

CollectPos 🔒

Enums

UsePreAttrPos 🔒

Functions

has_cfg_or_cfg_attr 🔒
