A modern programming language that makes developers happier.

kotlinlang

Is there any functional difference between
```@PostMapping
suspend fun uploadFile(@RequestParam file: Mono&lt;FilePart&gt;)```
and
```@PostMapping
suspend fun uploadFile(@RequestParam file: FilePart)```
other than maybe allow the former to not pass any value?

Does your first example actually work? I was under the impression that Spring 'translated' Mono/Flux to suspend variants behind the scenes.

e.g.
```@PostMapping
fun uploadFile(@RequestParam file: Mono&lt;FilePart&gt;)```
to
```@PostMapping
suspend fun uploadFile(@RequestParam file: FilePart)```
