lib.functionArgs

Extract the expected function arguments from a function. This works both with nix-native { a, b ? foo, ... }: style functions and functions with args set with setFunctionArgs. It has the same return type and semantics as builtins.functionArgs.

Type

functionArgs : (a -> b) -> Map String Bool

Inputs

f

1. Function argument
