Type::Tiny::Duck - type constraints based on the "can" method

This module is covered by the Type-Tiny stability policy.

Type constraints of the general form "{ $_->can("method") }".

This package inherits from Type::Tiny; see that for most documentation. Major differences are listed below:

"methods"
An arrayref of method names.
"constraint"
Unlike Type::Tiny, you cannot pass a constraint coderef to the constructor. Instead rely on the default.
"inlined"
Unlike Type::Tiny, you cannot pass an inlining coderef to the constructor. Instead rely on the default.
"parent"
Parent is always Types::Standard::Object, and cannot be passed to the constructor.

"stringifies_to($constraint)"
See Type::Tiny::ConstrainedObject.
"numifies_to($constraint)"
See Type::Tiny::ConstrainedObject.
"with_attribute_values($attr1 => $constraint1, ...)"
See Type::Tiny::ConstrainedObject.

Please report any bugs to <http://rt.cpan.org/Dist/Display.html?Queue=Type-Tiny>.
