Specio::Subs - phpMan

NAME
    Specio::Subs - Make validation and coercion subs from Specio types

VERSION
    version 0.47

SYNOPSIS
      use Specio::Subs qw( Specio::Library::Builtins Specio::Library::Perl My::Lib );

      if ( is_PackageName($var) ) { ... }

      assert_Str($var);

      my $person1 = to_Person($var);
      my $person2 = force_Person($var);

DESCRIPTION
    This module generates a set of helpful validation and coercion
    subroutines for all of the types defined in one or more libraries.

    To use it, simply import "Specio::Subs" passing a list of one or more
    library names. This module will load those libraries as needed.

    If any of the types in any libraries have names that do not work as part
    of a Perl subroutine name, this module will throw an exception.

    If you have Sub::Util or Sub::Name installed, one of those will be used
    to name the generated subroutines.

"EXPORTS"
    The following subs are created in the importing package:

  is_$type($value)
    This subroutine returns a boolean indicating whether or not the $value
    is valid for the type.

  assert_$type($value)
    This subroutine dies if the $value is not valid for the type.

  to_$type($value)
    This subroutine attempts to coerce $value into the given type. If it
    cannot be coerced it returns the original $value.

    This is only created if the type has coercions.

  force_$type($value)
    This subroutine attempts to coerce $value into the given type, and dies
    if it cannot do so.

    This is only created if the type has coercions.

ADDITIONAL API
    This module has a subroutine named "subs_installed_into". It is not
    exported but it can be called by its fully qualified name. It accepts a
    single argument, a package name. It returns a list of subs that it
    generated and installed in the given package, if any.

    This exists to make it easy to write a type library that combines other
    library and generates helper subs for export all at once.
