Description
I was in the middle of swapping the 'tokio_postgres' library for 'sqlx'. After rewriting my main db connector function I proceeded to unceremoniously hack away all the use statements for the old library so that the linter may tell me where there's still any dependencies left in the code. This compiler bug (as the message in the backtrace tells me) is a result of all that reckless abandon.
Please also note that I included two separate backtrace messages as somehow the one with RUST_BACKTRACE=1 seemed less detailed to me.
Code
#[derive(Debug)]
pub(crate) enum Command {
(...)
// after changing 'Row' to the unit type '()' the compiler is happy again
// before me deleting the use statement, it used to refer to 'tokio_postgres::Row'
GetBesties {
re: oneshot::Sender<Result<Vec<Row>, sqlx::Error>>,
},
(...)
