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 ​ $type−>check({foo=>1}); # false
STATUSThis module is covered by the Type-Tiny stability policy.
DESCRIPTIONGenerally speaking, you probably don't want to be using this module directly. Instead use the lookup method from Type::Registry which wraps it.
Functionsparse($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.
ConstantsThe following constants correspond to values returned by $token−>type. TYPE QUOTELIKE STRING CLASS L_BRACKET R_BRACKET COMMA SLURPY UNION INTERSECT NOT L_PAREN R_PAREN MYSTERY
