To handle errors in a Rust Salvo web API, you can implement custom error types with Writer implementations to render standardized JSON error payloads and map them using StatusError to appropriate HTTP status codes.

CatchPanic works by intercepting panics in your Rust API handlers, converting them into controlled responses and logs to ensure safe, centralized failure management and prevent server crashes.

You can return consistent JSON error responses from Salvo middleware by building custom error types that implement the Writer trait, ensuring structured and standardized payloads across all handlers.

Yes, Salvo supports mapping custom business errors to HTTP status codes using StatusError-based maps, allowing you to translate system and business logic failures into accurate REST API responses.

The best way to structure error handling in a Salvo REST API is to combine custom error types for standardized JSON payloads with CatchPanic for global safety, ensuring clear diagnostics and safer control flow.

Unhandled panics crash your Salvo API because they propagate without interception; you can prevent this by applying CatchPanic middleware to convert panics into controlled JSON responses and logs.
