Common Patterns

Idiomatic error handling

The standard error handling pattern:

result, err := doSomething()
if err != nil {
    return fmt.Errorf("doing something: %w", err)
}
// Use result

Check immediately, wrap with context, return. Keep the happy path at the left margin. Error handling is indented.
