The language uses enums with data, pattern matching, and the Result type to catch errors at compile time rather than runtime. Features like the question mark operator for error propagation, move semantics by default, and consuming methods enable the compiler to enforce correct API usage. This strong static typing reduces the need for unit tests, makes refactoring safer and faster, and ensures that code that compiles is more likely to work as intended. ## Full article daily.dev links to this article rather than hosting it.
