# Type::Tiny::XS(3pm)

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

## 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 three 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.
