NAME

Type::Tiny::XS - provides an XS boost for some of Type::Tiny's built-in type constraints

SYNOPSIS

   use Types::Standard qw(Int);

DESCRIPTION

This module is optionally used by 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:

Type::Tiny::XS::get_coderef_for($type)

Given a supported type constraint name, such as "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.

Type::Tiny::XS::get_subname_for($type)

Like 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.

Type::Tiny::XS::is_known($coderef)

Returns true if the coderef was provided by Type::Tiny::XS.

In addition to the above functions, the subs returned by get_coderef_for and 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 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.
