Split off function call to make pattern match clearer (#2785)

Browse Source 
I think doing the call to `Duration::try_from_secs_f32` in the pattern
match is a bit verbose since the function name is so long. I usually
split this off into a separate variable so that it's easier to see the
pattern match syntax.

@ -8,7 +8,9 @@ lets you execute different code depending on whether a value matches a pattern:
use std::time::Duration; use std::time::Duration;
fn sleep_for(secs: f32) { fn sleep_for(secs: f32) {
if let Ok(duration) = Duration::try_from_secs_f32(secs) { let result = Duration::try_from_secs_f32(secs);
if let Ok(duration) = result {
std::thread::sleep(duration); std::thread::sleep(duration);
println!("slept for {duration:?}"); println!("slept for {duration:?}");
} }
