DESCRIPTIONA structure is a set of Moose::Meta::TypeConstraint that are 'aggregated' in such a way as that they are all applied to an incoming list of arguments. The idea here is that a Type Constraint could be something like, "An "Int" followed by an "Int" and then a "Str"" and that this could be done so with a declaration like:
Tuple[Int,Int,Str]; ## Example syntax
So a structure is a list of type constraints (the "Int,Int,Str" in the above example) which are intended to function together.
type_constraintsA list of Moose::Meta::TypeConstraint objects.
validateMessing with validate so that we can support nicer error messages.
generate_constraint_for ($type_constraints)Given some type constraints, use them to generate validation rules for an ref of values (to be passed at check time)
parameterize (@type_constraints)Given a ref of type constraints, create a structured type.
compile_type_constrainthook into compile_type_constraint so we can set the correct validation rules.
create_child_typemodifier to make sure we get the constraint_generator
equalsOverride the base class behavior.
type_constraints_equalsChecks to see if the internal type constraints are equal.
get_messageGive you a better peek into what's causing the error. For now we stringify the incoming deep value with Devel::PartialDump and pass that on to either your custom error message or the default one. In the future we'll try to provide a more complete stack trace of the actual offending elements
A subref or closure that contains the way we validate incoming values against a set of type constraints.
This returns a CODEREF which generates a suitable constraint generator. Not user servicable, you'll never call this directly.
