Function that would typically be named `assumeXXX`. ... That way, @safe code will still need to manually @trust them. I basically wanted some kind of functionality similar to this but with regards to the GC. Like some way to annotate a function as @WillAllocate or something, and forbid calling it unless the caller function explicitly acknowledged the allocation (without having to wrap everything in @nogc). Just for fun I experimented with a locking GC that used the struct/dtor model to open/re-lock.

(It as a weird issue where I was trying to add a command to an app and because the %1 parameter didn't have quotes I guess it deleted the D folder as it shortened it to D) I had a backup and didn't change anything since then except for updating the compilers. Still had the same visual D version. So I copied it over and updated dmd with visual D. Everything worked fine that day and I messed with the code several times. Woke up and wanted to make a simple change and code would not compile. The changes were insignificant. It gave me that error and when I added that switch then I got one about pragma(crt_constuctor) needing extern(C). Anyways, tried adding the extern(C) in the code but it wouldn't accept the changes. BUT I just tried to compile it again and no issues. Probably drive corruption issues or possibly some type of caching issue. But I was able to make changes now and compile it like it should work. E.g., it's possible that when I copied over the old D directory that it had an old compiler(I think it was from '22). I did update with visual D but maybe there was caching going on that was causing the conflict. In any case everything seems to be back to normal. I really didn't do much to fix anything so it was probably all caused by deleting that D folder accidentally.

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);
}
}

It’s done when the download() returns. Pretty sure it is not synchronous. I'm running it many times. Maybe it is synchronous and I just didn't notice.
range shortened method not enabled, compile with compiler switch `-preview=shortenedMethods`
For absolutely no reason I started getting this error. Last night I compiled the project and it worked just fine. This morning I made a single insignificant change and tried to compile and got that error. Only possible thing is that for some reason some change in updating the compiler may have no propagated correctly till after the reboot. when I add the switch I then get. function `core.time.TickDuration.time_initializer` must be `extern(C)` for `pragma(crt_constructor)` dmd-2.105.2 EVERYTHING was working fine yesterday. All I did today was load up the project and change an integer value and I couldn't compile it ;/ Maybe corruption somewhere, I don't know. Anyways, I added extern(C) to that method in the location it says the file exists but no change. I removed the pragma, no change. Doesn't seem to actually be using that file. I have no idea what is going on. All I can do is try to reinstall the compiler and maybe redo the dub package. I'm using visual D + vibe.d + dub. Nothing fancy.

There is a callback for the streaming side but not for the file download. If you want an asynchronous download just create a task or use spawn. Apparently there's also this in vibe: https://vibed.org/api/vibe.core.concurrency/async
