Incorrect imports suggestion for code inside tokio::main #86241
Description
Given the following code:
#[tokio::main]
async fn main() {
let _ = Duration::from_millis(97);
}The current output is:
error[E0433]: failed to resolve: use of undeclared type `Duration`
--> src/main.rs:3:13
|
3 | let _ = Duration::from_millis(97);
| ^^^^^^^^ not found in this scope
|
help: consider importing one of these items
|
2 | async use chrono::Duration;
| ^^^^^^^^^^^^^^^^^^^^^
2 | async use core::time::Duration;
| ^^^^^^^^^^^^^^^^^^^^^^^^^
2 | async use humantime::Duration;
| ^^^^^^^^^^^^^^^^^^^^^^^^
2 | async use instant::Duration;
| ^^^^^^^^^^^^^^^^^^^^^^
and 5 other candidates
Note the async use bit, which is, obviously, invalid syntax.

Thanks for the report!
Even fixing the
asyncpart won't be sufficient because the#[tokio::main]attribute is in the way, too. There is more discussion at #85312 (comment) and #85427 as to why that doesn't work.pnkfelix commentedon Nov 16, 2021
(This is probably fixed by proposed PR #90941.)

Just checked in playground - seems to be fixed for now, probably should be closed?

Yea, I'm going to close as resolved by #94584.
