Type::Tiny::Duck

type constraints based on the "can" method

Status

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

Description

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

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

Attributes

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.
