NAME

Types::TypeTiny - type constraints used internally by Type::Tiny

STATUS

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

DESCRIPTION

Dogfooding.

This isn't a real Type::Library-based type library; that would involve too much circularity. But it exports some type constraints which, while designed for use within Type::Tiny, may be more generally useful.

Types

StringLike

Accepts strings and objects overloading stringification.

HashLike

Accepts hashrefs and objects overloading hashification.

ArrayLike

Accepts arrayrefs and objects overloading arrayfication.

CodeLike

Accepts coderefs and objects overloading codification.

TypeTiny

Accepts blessed the Type::Tiny manpage objects.

Coercion Functions

to_TypeTiny($constraint)

Promotes (or ``demotes'' if you prefer) a Moose::Meta::TypeConstraint object to a Type::Tiny object.

Can also handle the Validation::Class manpage objects. Type constraints built from Validation::Class objects deliberately ignore field filters when they do constraint checking (and go to great lengths to do so); using filters for coercion only. (The behaviour of coerce if we don't do that is just too weird!)

Can also handle any object providing check and get_message methods. (This includes the Mouse::Meta::TypeConstraint manpage objects.) If the object also provides has_coercion and coerce methods, these will be used too.

Can also handle coderefs (but not blessed coderefs or objects overloading &{}). Coderefs are expected to return true iff $_ passes the constraint. If $_ fails the type constraint, they may either return false, or die with a helpful error message.

Methods

These are implemented so that Types::TypeTiny->meta->get_type($foo) works, for rough compatibility with a real the Type::Library manpage type library.
