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);

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.
