NAME

       SQL::Translator::Types - Type checking functions

SYNOPSIS

           package Foo;
           use Moo;
           use SQL::Translator::Types qw(schema_obj enum);

           has foo => ( is => 'rw', isa => schema_obj('Trigger') );
           has bar => ( is => 'rw', isa => enum([qw(baz quux quuz)], {
               msg => "Invalid value for bar: '%s'", icase => 1,
           });

DESCRIPTIONS

       This module exports functions that return coderefs suitable for Moo "isa" type checks.
       Errors are reported using "throw" in SQL::Translator::Utils.

FUNCTIONS

   schema_obj($type)
       Returns a coderef that checks that its arguments is an object of the class
       "SQL::Translator::Schema::$type".

   enum(\@strings, [$msg | \%parameters])
       Returns a coderef that checks that the argument is one of the provided @strings.

       Parameters

       msg sprintf string for the error message.  If no other parameters are needed, this can be
           provided on its own, instead of the %parameters hashref.  The invalid value is passed
           as the only argument.  Defaults to "Invalid value: '%s'".

       icase
           If true, folds the values to lower case before checking for equality.

       allow_undef
           If true, allow "undef" in addition to the specified strings.

       allow_false
           If true, allow any false value in addition to the specified strings.
