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
o StringLike

Accepts strings and objects overloading stringification.

o HashLike[`a]

Accepts hashrefs and objects overloading hashification.

Since Types::TypeTiny 1.012, may be parameterized with another type constraint like
HashLike[Int].

o ArrayLike[`a]

Accepts arrayrefs and objects overloading arrayfication.

Since Types::TypeTiny 1.012, may be parameterized with another type constraint like
ArrayLike[Int].

o CodeLike

Accepts coderefs and objects overloading codification.

o TypeTiny

Accepts blessed Type::Tiny objects.

o _ForeignTypeConstraint

Any reference which to_TypeTiny recognizes as something that can be coerced to a
Type::Tiny object.

Yes, the underscore is included.

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)"
