Error-Handling

Building production-grade services requires more than just functionality—they need resilience, graceful degradation, and the ability to handle failures without crashing. In this post, we’ll build a robust logging service that demonstrates these principles using Go’s context package and proper error handling. The Problem Imagine your application sends logs to a remote logging service. What happens when: The logging service is slow or unresponsive? Network issues cause delays? The logging service crashes entirely? Without proper safeguards, your entire application could hang, crash, or become unresponsive just because logging failed. Logging should never bring down your application. ...

Go to Rust Series: ← String vs &str | Series Overview The Problem: Nil and Errors Tony Hoare (inventor of null references) called it his “billion-dollar mistake.” Go’s approach: nil values and explicit error returns Rust’s approach: Option<T> for absence, Result<T, E> for errors Go: Nil Pointers Go: func findUser(id int) *User { if id == 0 { return nil } return &User{ID: id, Name: "Alice"} } func main() { user := findUser(0) if user != nil { fmt.Println(user.Name) } else { fmt.Println("User not found") } } Problem: Easy to forget nil check: ...
