=head1 NAME
Type::Tiny::XS - provides an XS boost for some of Type::Tiny's built-in type constraints
=head1 SYNOPSIS
use Types::Standard qw(Int);
=head1 DESCRIPTION
This module is optionally used by L<Type::Tiny> 0.045_03 and above
to provide faster, C-based implementations of some type constraints.
(This package has only core dependencies, and does not depend on
Type::Tiny, so other data validation frameworks might also consider
using it!)
Only the following two functions should be considered part of the
supported API:
=over
=item C<< Type::Tiny::XS::get_coderef_for($type) >>
Given a supported type constraint name, such as C<< "Int" >>, returns
a coderef that can be used to validate a parameter against this
constraint.
Returns undef if this module cannot provide a suitable coderef.
=item C<< Type::Tiny::XS::get_subname_for($type) >>
Like C<get_coderef_for> but returns the name of such a sub as a string.
Returns undef if this module cannot provide a suitable sub name.
=item C<< Type::Tiny::XS::is_known($coderef) >>
Returns true if the coderef was provided by Type::Tiny::XS.
=back
In addition to the above functions, the subs returned by
C<get_coderef_for> and C<get_subname_for> are considered part of the
"supported API", but only for the lifetime of the Perl process that
returned them.
To clarify, if you call C<< get_subname_for("ArrayRef[Int]") >> in a
script, this will return the name of a sub. That sub (which can be used
to validate arrayrefs of integers) is now considered part of the
supported API of Type::Tiny::XS until the script finishes running. Next
time the script runs, there is no guarantee that the sub will continue
to exist, or continue to do the same thing.
