SYNOPSIS

        use strict;

        use Type::Parser qw( eval_type );
        use Type::Registry;

        my $reg = Type::Registry->for_me;
        $reg->add_types("Types::Standard");

        my $type = eval_type("Int | ArrayRef[Int]", $reg);

        $type->check(10);        # true

STATUS

       This module is covered by the Type-Tiny stability policy.

DESCRIPTION

       Generally speaking, you probably don't want to be using this module directly.  Instead use
       the "lookup" method from Type::Registry which wraps it.

   Functions
       "parse($string)"
           Parse the type constraint string into something like an AST.

           If called in list context, also returns any "tail" found on the original string.

       "extract_type($string, $registry)"
           Compile a type constraint string into a Type::Tiny object.

           If called in list context, also returns any "tail" found on the original string.

       "eval_type($string, $registry)"
           Compile a type constraint string into a Type::Tiny object.

           Throws an error if the "tail" contains any non-whitespace character.

   Constants
       The following constants correspond to values returned by "$token->type".

       "TYPE"
       "QUOTELIKE"
       "STRING"
       "HEXNUM"
       "CLASS"
       "L_BRACKET"
       "R_BRACKET"
       "COMMA"
       "SLURPY"
       "UNION"
       "INTERSECT"
       "NOT"
       "L_PAREN"
       "R_PAREN"
       "MYSTERY"
