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

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

tokens($string)

Tokenize the type constraint string; returns a list of tokens.

parse($string), parse($arrayref_of_tokens)

Parse the type constraint string into something like an AST.

eval_type($string, $registry), eval_type($arrayref_of_tokens, $registry)

Compile the type constraint string into a Type::Tiny object.

Constants

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