`adt_sized_constraint` called on non-struct type

[Dig-Doug]

Code

Note: Error is in big private project, I can follow up with a smaller example this weekend.

Sharing a rough outline now of what I think is relevant:

#[derive(Debug, Clone)]
pub enum SourceDocument {
  Document {
    source: SourceDocumentModel,
  },
}

#[async_graphql::Object]
impl SourceDocument {
  async fn version_id(&self) -> Uuid {
    match self {
      SourceDocument::Document { source } => source.version_id.clone(),
    }
  }
}

pub struct SourceDocumentLoader {
  pub pool: ReadDbPool,
}

impl Loader<Uuid> for SourceDocumentLoader {
  type Value = SourceDocument;
  type Error = LoaderError;

  async fn load(&self, keys: &[Uuid]) -> Result<HashMap<Uuid, Self::Value>, Self::Error> {
    // Uses diesel to read from a postgres db
    todo!()
  }
}

#[derive(thiserror::Error, Clone, Debug)]
pub enum LoaderError {
  #[error("Error loading data: {message}")]
  Error { message: String },
}

#[derive(Debug, Clone, Queryable, Selectable, Insertable)]
#[diesel(table_name = crate::schema::source_documents)]
#[diesel(check_for_backend(diesel::pg::Pg))]
#[diesel(primary_key(version_id))]
pub struct SourceDocumentModel {
    pub version_id: Uuid,
}

Code uses async_graphql, diesel, and thiserror.

How to reproduce this error? Right now, ReadDbPool and crate::schema::source_documents are not defined (and I didn't find ReadDbPool in any of the dependencies). Adding your Cargo.toml can also help to get the right versions and features of dependencies.

[Dig-Doug]

Apologies, I'm having trouble reproducing this issue in my main project despite restoring to the previous state. Nevertheless, I created a small project that includes the things I think are referenced in the backtrace here to illustrate the project structure.

Notes

#15 collect_return_position_impl_trait_in_trait_tys(lobbying_server[564e]::{impl#3}::resolve_field)
#16 type_of(lobbying_server[564e]::{impl#3}::{synthetic#0})
#17 check_well_formed(lobbying_server[564e]::{impl#3})
#18 check_mod_type_wf(lobbying_server[564e])

I assume this is processing the Query struct which includes the GetNodeQuery struct.

#0 type_of(lobbying_server[564e]::node::_#3::{impl#2}::{synthetic#0})

node is the file that contains the GetNodeQuery code.

#0 [adt_sized_constraint] computing the `Sized` constraint for `source_document::SourceDocument`
#1 [evaluate_obligation] evaluating trait selection obligation `{coroutine witness@async_graphql::dataloader::DataLoader<source_document::SourceDocumentLoader>::load_one<uuid::Uuid>::{closure#0}}: core::marker::Send`
end of query stack

Inside the node implementation, it accesses the SourceDocumentLoader and calls the load_one fn.

[lukas-code]

This is a bug in the compiler's incremental compilation engine. To reproduce it you need to run cargo check, change something, and then run cargo check again. Also it should go away after a cargo clean.

If you manage to retrace the changes that you did to your codebase and actually get this to reproduce that would be very helpful, but without a repro there is not much we can do here.

(And this ICE can also happen if you somehow got a bit flipped in your incremental files.)

@rustbot label A-incr-comp S-needs-repro

[Dig-Doug]

Aha! Thank you for that info, that was the info I needed.

I am now able to reproduce by going to src/source_document.rs and changing the struct:

#[derive(Debug, Clone)]
pub struct SourceDocument {
    source: SourceDocumentModel,
}

to

#[derive(Debug, Clone)]
pub enum SourceDocument {
    Document { source: SourceDocumentModel },
}

I get:
