It would be nice to have this code working, is not it?
if let Some(time_string) = servak.time_string() && !time_string.is_empty() {
f = f.field("Time", &time_string, true);
}
Now I need to write noisy code:
if let Some(time_string) = servak.time_string() {
if !time_string.is_empty() {
f = f.field("Time", &time_string, true);
}
}
There is discussions on how to improve expressiveness of if-let patterns, but nothing concrete yet.

Note that in the meantime you can reduce excess indentation using https://crates.io/crates/if_chain
if_chain! {
if let Some(time_string) = servak.time_string();
if !time_string.is_empty();
then {
f = f.field("Time", &time_string, true);
}
}
(Please excuse any typos in the above; I didn't compile it.)
