Support for Diesel 2.0?

[phayes]

Hi there,

I was wondering if there are any plans to support diesel 2? I would be willing to pay for this development if required.

Hey, thanks for the offer. I am willing to do this for free since I need it myself too, so I whipped up a branch that you can use until Diesel 2.0 comes out: feat/diesel-2.0. Let me know if you run into anything :)

Hey @ThouCheese ,

So far so good. One issue I'm running into on this is supporting the new #[diesel(sql_type = SomeType)]type annotation instead of the deprecated #[sql_type = "SomeType"] notation

[ThouCheese]

Hey there @phayes, sorry about dropping off the radar for a little there. I've pushed another change that modifies the attributes to look like this:

#[derive(Debug, Clone, Copy, PartialEq, Eq, diesel::deserialize::FromSqlRow, DbEnum)]
#[diesel(sql_type = SmallInt)]
#[diesel_enum(error_fn = CustomError::not_found)]
#[diesel_enum(error_type = CustomError)]
pub enum Status {
    /// Will be represented as 0.
    Ready,
    /// Will be represented as 1.
    Pending,
}

I'm no master of proc macros, so it doesn't produce the best error messages, but let me know what you think!

@ThouCheese,

I just updated to the branch, things are compiling. I will be able to report back in the near future if things are working correctly.

With Diesel now at 2.1.0, what are the odds of getting this merged into the current crate?

@zdannar @peschkaj @phayes Support for diesel 2.0 is now on master and on crates.io! Find it at version 0.2.1
