SQL::Tr...::Error(3)

okay so bestie, welcome to SQL::Tr...::Error(3) — it's part of the User Contributed Perl Documentation crowd, and it's here to teach you the error setter/getter vibe for objects and classes. 💖

---

🌸 NAME 🌸

SQL::Translator::Role::Error — the error setter/getter for objects and classes. no cap, that's literally the whole job. ✨

---

✨ SYNOPSIS ✨

In the class that's consuming the role, it looks like this:

package Foo;
use Moo;
with qw(SQL::Translator::Role::Error);

sub foo {
    ...
    return $self->error("Something failed")
        unless $some_condition;
    ...
}

And in code that's using the class, you can do either of these:

Foo->foo or die Foo->error;
# or
$foo->foo or die $foo->error;

---

💖 DESCRIPTION 💖

This Moo::Role provides a method for getting and setting error on a class or object. That's the whole main character energy of this page. 💅

---

🎀 METHODS 🎀

💅 $object_or_class->error([$message]) 💅

If you call it with an argument, it sets the error message and returns undef. If you call it without an argument, it returns the message. Slay. 🫶

As an implementation detail — and yes, for compatibility with Class::Base — the message is stored in $object->{_ERROR} or $Class::ERROR, depending on whether the invocant is an object. iykyk. 🧚
