Description
Code
Inside of an async function, make some kind of syntax error, like calling a function that doesn't exist or was not yet imported.
Current output
This produces a very large amount of output:
Checking flippy v0.1.0 (/Users/james/personal/erdnuss/host/flippy)
error[E0425]: cannot find function `esteban` in this scope
--> src/dom_worker.rs:102:13

102 | esteban();

error: future cannot be sent between threads safely

160 | ...k::spawn(runtil(ctxt.clone(), wrx, device)),

note: this item depends on auto traits of the hidden type, but may also be registering the hidden type. This is not supported right now. You can try moving the opaque type and the item that actually registers a hidden type into a new submodule

139 | async fn watch_devices(ctxt: Arc<Context>) {

note: future is not `Send` as this value is used across an await

For more information about this error, try `rustc --explain E0425`.
error: could not compile `flippy` (bin "flippy") due to 3 previous errors
In particular in the console, ONLY the first error is useful, the rest is just noise.
Desired output
Just the first error, please:
error[E0425]: cannot find function `esteban` in this scope
--> src/dom_worker.rs:102:13
|
102 | esteban();
| ^^^^^^^ not found in this scopeRationale and extra context
This is what it looks like graphically, at the moment.
Other cases
