NAME

GraphQL::MaybeTypeCheck - Conditional type-checking at runtime

SYNOPSIS

            

              
              
use GraphQL::MaybeTypeCheck;
method foo(
  $arg1 Str,
  $arg2 Int
) :ReturnType(Map[Str, Int]) {
  # ...
}
            
          

DESCRIPTION

This module optionally enables type-checking in the caller as implemented by Function::Parameters and Return::Type depending on whether Devel::StrictMode is activated.

Devel::StrictMode ON

When Devel::StrictMode is active, this module will import Function::Parameters into the caller with its default configuration. As of writing, this includes checking both argument count and type.

When in strict mode this also requires Return::Type which registers the ReturnType attribute.

Devel::StrictMode OFF

When strict mode is inactive this module still imports Function::Parameters into the caller however it sets fun and method to lax mode and disables argument type checking.

This also installs a no-op ReturnType attribute so the existing syntax isn't broken.
