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 Type::Tiny 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 Validation::Class 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 Mouse::Meta::TypeConstraint 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 Type::Library type library.

"meta"

"type_names"

"get_type($name)"

"has_type($name)"

"coercion_names"

"get_coercion($name)"

"has_coercion($name)"
