I do know about

const x: u32 = @truncate(an_u64_val);
const what_I_want: u64 = @intCast(x);

but that is quite long. Is there a shorter way for that?

#

Slightly smaller I found is @intCast(@as(u32, @truncate(an_u64_val)))

nope, that's kinda how you have to do it, either create separate variables or use @as

tropic vector
#

you could also do

const x: i64 = @bitCast(u64_val)
#

if you're certain that it will fit in an i64

make a helper function, you can make it a single character if thats what you want.

# 
fn a(in: u64) i64 {
  return @intCast(in);
}

Now using only 3 characters you can cast anything you want. Cant get much shorter than that. a(...)

80 character column lengths saved, hundreds of hours wasted in key strokes prevented, world peace achieved, or something like that idk.
