MooX::TypeTiny - Optimized type checks for Moo + Type::Tiny


  package Some::Moo::Class;
  use Moo;
  use MooX::TypeTiny;
  use Types::Standard qw(Int);

  has attr1 => (is => 'ro', isa => Int);


This module optimizes Moo type checks when used with Type::Tiny to perform better. It will automatically apply to isa checks and coercions that use Type::Tiny. Non-Type::Tiny isa checks will work as normal.

This is done by inlining the type check in a more optimal manner that is specific to Type::Tiny rather than the general mechanism Moo usually uses.

With this module, setters with type checks should be as fast as an equivalent check in Moose.

It is hoped that eventually this type inlining will be done automatically, making this module unnecessary.
