I'm using download(url, filename) to download files in vibe.d.
The issue is that I do not know when the download is finished or
errors. There is a callback for the streaming side but not for the
file download.
A small test program shows, that if the function return normally the
transfer was done (and the file saved).
The function raises an exception if there is e,g, an http error status
communicated.
I am not sure what happens if the download is interrupted in the
middle. I guess there will be an exception, but the file might be
written partially.
Kind regards,

I can't do any testing because overnight for no explicable reason the
app will not compile any more.
If it is synchronous then I should be able to do what I need without
issue. When I initially was using it and the way the app works it seemed
like it was running in parallel because I didn't see it execute
synchronously because the tasks were relatively short and I just thought
it was asynchronous for some reason(I didn't give it any thought at the
time until I got errors in the download and needed to make the code more
robust but I can't do anything until I figure out why the code no longer
compiles(I made a post about it but it's not showing up yet).
minimal program to test the behavior (although with fibers it might be
tricky to see whats really going on .. perhaps try to do two downloads
after each other and see how the program behaves):
```d
import vibe.vibe;
import std.stdio : writeln;
void main(string[] args)
{
try {
download(args[1], args[2]);
} catch (Exception e)
{
writeln("puh: ", e);
}
}
```
Kind regards,
Christian
