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 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($constraint)
-
Promotes (or "demotes" if you prefer) a Moose::Meta::TypeConstraint object to a Type::Tiny object.
Can also handle Validation::Class objects. Type constraints built from Validation::Class objects deliberately ignore field filters when they do constraint checking (and go to great lengths to do so); using filters for coercion only. (The behaviour of
coerce
if we don't do that is just too weird!)Can also handle any object providing
check
andget_message
methods. (This includes Mouse::Meta::TypeConstraint objects.) If the object also provideshas_coercion
andcoerce
methods, these will be used too.Can also handle coderefs (but not blessed coderefs or objects overloading
&{}
). Coderefs are expected to return true iff$_
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.
