Module trait_signature 

Infer inherited argument types from a concrete method item, not copied paths.

Functions

argument_ident 🔒

callable 🔒

Unsafe or foreign-ABI methods are not FnOnce items. A never-called closure presents their argument types to the same inference helper.

setup 🔒

This local generic function only inspects a callable’s signature. It never calls it, constructs an argument, or adds conversion bounds to the trait.
