Type::Parser - parse type constraint strings
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 $type->check({foo=>1}); # false
This module is covered by the Type-Tiny stability policy.
Generally speaking, you probably don't want to be using this module directly. Instead use the lookup method from Type::Registry which wraps it.
lookup
parse($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, $registry)
Compile a type constraint string into a Type::Tiny object.
eval_type($string, $registry)
Throws an error if the "tail" contains any non-whitespace character.
The following constants correspond to values returned by $token->type.
$token->type
TYPE
QUOTELIKE
STRING
CLASS
L_BRACKET
R_BRACKET
COMMA
SLURPY
UNION
INTERSECT
NOT
L_PAREN
