Struct AttrWithUnknown 

pub struct AttrWithUnknown { /* private fields */ }

Available on crate feature attributes only.

Low-level attribute parser used internally by the attribute extraction macros.

You should not use this type directly. Use [get_attributes!] or [fields_get_attributes!] instead.

This type is exported for technical reasons (used by the proc macro crate) but is not part of the stable API. Implementation details may change without notice.
