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 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.
