NAME
    Type::Parser - parse type constraint strings

SYNOPSIS
     use v5.10;
     use strict;
     use warnings;

     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
     $type->check([1..4]);    # true
     $type->check({foo=>1});  # false

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"
