NAME

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

DESCRIPTION

Dogfooding.

This isn't a real Type::Library-based type library; that would involve too much circularity. But it exports some type constraint "constants":

Types

StringLike
HashLike
ArrayLike
CodeLike
TypeTiny

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
get_type($name)
