Simplify control flow #16
Description
Use of options coupled with the current unwrapping strategy can render the code hard to follow. We should identify where guards could be more appropriate:
fn main() {
let option_1 = Some(42);
let option_2 = Some(32);
// with if..
if let Some(val_1) =option_1 {
if let Some(val_2) = option_2 {
// 2-block depth
println!("{val_1} {val_2}")
}
}
// val_1 & val_2 leave scope...
// Use guards instead
let Some(val_1) = option_1 else { return };
let Some(val_2) = option_2 else { return };
// and values are still in the scope !
println!("{val_1} {val_2}")
}
