navi

Navi error handling uses throws to declare throwing functions and do-catch blocks to intercept them. You write a throwing function by marking it with throws, then handle potential failures explicitly within a do-catch scope during execution.

Navi concurrency leverages spawn to execute asynchronous tasks and channels to communicate between them. You initiate a concurrent operation by spawning a thread and passing data securely through typed channels to synchronize state across concurrent processes.

The Navi type system handles optional values by explicitly wrapping types that might be absent. You declare an optional by appending the optional modifier to the type, forcing the compiler to ensure null checks are performed before unwrapping and accessing the underlying value.

Navi is fully suitable for feature design and code review, providing guidance on syntax, module systems, and type safety. You can validate architectural patterns, review code correctness, and debug complex implementations using practical examples and official documentation references.

A Navi main function needs to throw when it calls other functions marked with throws that might fail. Declaring main() throws ensures any unhandled errors propagate correctly to the runtime environment, allowing the system to catch unrecoverable failures safely.

The Navi module system organizes code into reusable namespaces but requires strict adherence to visibility rules and import paths. You must ensure modules are correctly declared and imported to avoid compilation errors related to undefined references or circular dependencies.
