Traits

AttrParse

The AttrParse trait is a generic interface for attribute structures. This is only implemented directly by the crate::def_attrs macro, within the zbus_macros crate. This macro allows the parsing of multiple variants when using the crate::old_new macro pattern, using <T: AttrParse> as a bounds check at compile time.
