MooseX::Meta::TypeConstraint::Structured - Structured type constraints
A 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.
A list of Moose::Meta::TypeConstraint objects.
Messing with validate so that we can support nicer error messages.
Given some type constraints, use them to generate validation rules for an ref
of values (to be passed at check time)
Given a ref of type constraints, create a structured type.
hook into compile_type_constraint so we can set the correct validation rules.
modifier to make sure we get the constraint_generator
Override the base class behavior.
Checks to see if the internal type constraints are equal.
Give you a better peek into whats 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 well 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, youll never call this directly.
