.expect() (or .unwrap()) are not error handling mechanisms, and certainly not equivalent to if err != nil in Go. The usual error handling mechanism in Rust is the ? operators, that has the same meaning as if err == nil { return; }.
.expect()
.unwrap()
if err != nil
?
if err == nil { return; }
Would that be done like this?:
if let Err(Reason) = somefunc() { // handle error? }
Or match.
match
