__toString() in UuidInterface

[ramsey]

I'll add __toString() to version 4, but I can't add it to the interface on version 3.x, since that might break a lot of implementations.

I plan to make a big push to finish up all the things I want to implement for version 4 over the next couple of months. I'd like to have it out by the end of June.

No promises right now, but I'll consider the implications of adding __toString() to the UuidInterface to ensure that all UUIDs can be treated like a string.

Hey @jmauerhan

It's typically best in OOP to pass around objects rather than scalar values, so using the object instead of the string is a good idea.

Yeah, I pass objects around, but for serialization and representation in HTTP context I need to cast it to string. That's why all value objects that can be serialized to string tend to have a __toString() method.

you can typehint against the UuidInterface instead of Uuid, and you won't get that error message

But if I do that, I can't cast it to string because I can't make sure that __toString() method is implemented.

UuidInterface already has toString which is what Uuid::__toString calls. Maybe that will help? :)

That's what I do currently, but (string) $id just feels better :P so I'd like to have it possible in 4.0.

This would potentially fix a problem I have with api-platform where it doesn't know what to do with UuidInterface return values.
Would also possibly simplify integrations similar types of projects.

@ramsey any update on this? Would be nice to finally have this

I'm just looking into this as well, what is the right usage for Typehinting when you have a HEX instead if a dashed UUID ?

[ramsey]

When you cast the Uuid object to a string, it is presented in the dashed, hexadecimal format. For type-hinting, it is a string.

[Yamakasi]

OK, the class itself doesn't check for a valid string, that could be done on the construct, etc so you can typehint Uuid.

Or is it too much overhead to do that ? Could be added simply and is all in your library then.

@Yamakasi see Ramsey\Uuid\Exception\InvalidUuidStringException which gets thrown when you attempt to use Uuid::fromString() on an invalid Uuid
