Support for uuid::Uuid v >= 1.0.0

[onx2]

It looks like uuid just released version 1.0.0 and I tried switching and received this error:

the trait bound `uuid::Uuid: OutputType` is not satisfied
required because of the requirements on the impl of `OutputType` for `&uuid::Uuid`

on this struct I have with the derived SimpleObject

#[derive(SimpleObject, Serialize, Deserialize, Debug, FromDbModel)]
pub struct User {
    pub id: Uuid,
    pub email: String,
    ..
}

Two part question:

1. Could I temporarily resolve this by not using SimpleObject?
2. What would it take to support v1 of uuid / is this a good first issue for a Rust beginner?

Yes, welcome. 😁

Cool, I can give it a shot when I get back home from vacation. Any pointers on what this might take / where to start?

[sunli829]

I guess just need to update the uuid version and then fix possible compile errors.

Can we support both? There are still many crates that depend on < 1.0 and it might take a while until the ecosystem migrates to uuid 1.0 (Or at least support one of them by specifying a new feature like uuid-v1 and uuid-v0.8).

@sunli829 I'm still getting the same error with the async-graphql 4.0.0

@semanser That's because the sqlx release you are on (0.5.x) is still using uuid-0.8.x:

@cynecx Ah, you're right. I was checking it on master and it uses 1.0 already... thanks!
