NAME

MooX::Const - Syntactic sugar for creating constant Moo attributes

VERSION

version v0.1.0

SYNOPSIS

  use Moo;
  use MooX::Const;

  has thing => (
    is  => 'const',
    isa => ArrayRef[HashRef],
  );

DESCRIPTION

This is syntactic sugar for using Types::Const with Moo.

It modifies the has function to support "const" attributes. These are read-only ("ro") attributes for references, where the underlying data structure has been set as read-only.

This will return an error if there is no "isa", the "isa" is not a Type::Tiny type, if it is not a reference, or if it is blessed object.

Simple value types such as Int or Str are silently converted to read-only attributes.
