ICE: assertion failed: !ty.needs_infer() #112832

Marwes · 2023-06-20T08:52:08Z

I tried this code: (minimized)

pub trait QueryDb {
    type Db;
}

pub struct QueryTable<Q, DB> {
    db: DB,
    storage: Q,
}

impl<Q> QueryTable<Q, <Q as QueryDb>::Db> where Q: for<'d> AsyncQueryFunction<'d> {}

pub trait AsyncQueryFunction<'d>: QueryDb<Db = <Self as AsyncQueryFunction<'d>>::SendDb> {
    type SendDb: 'd;
}

pub trait QueryStorageOpsAsync<Q>
where
    Q: for<'d> AsyncQueryFunction<'d>,
{
}

fn main() {}

I expected to see this happen: It should compile as it does on rust 1.69 and earlier (or at least not ICE).

Instead, this happened: The program fails to compile with an ICE (see backtrace).

I have tried to fix compilation issue in gluon_salsa by explicitly specifying lifetimes, but I have ran into ICE.

I enjoy using gluon and would really like for this to be solved to enable using it with the current compiler. Hopefully this helps
