Rust-Analyzer is reporting a false `type-mismatch` error

[winksaville]

I'm using vscode and I have a situation where code that compiles and runs fine, but Rust Analyzer is reporting an error, type-mismatch. This happens both on nightly and stable.

This happens at call sites "using" sender_map_insert. So there are no errors in sender_map_by_instance_id/src/lib.rs where sender_map_insert is defined, but RA reports the false error in all other cases below. By default this workspace is compiled with nightly, you can change rust-toolchain.toml to stable and the false error occurs in both cases. (When changing to stable you'll need disable the first line in /msg_header/src/lib.rs #![feature(downcast_unchecked)] // Disable if stable)
