Struct Error

pub struct Error { /* private fields */ }

Represents a JSON-RPC error that the server may send as a response.

This type contains both the standard JSON-RPC error fields (code, message, data) and an optional std::error::Error source for additional context. Depending on the build configuration (cfg!(debug_assertions)) or certain Session settings, debug builds typically include the source error to facilitate troubleshooting, while release builds omit it to prevent leaking internal information.

Notes

• This error type can be automatically created from any std::error::Error using the ? operator, similarly to anyhow.
• Serialization is intentionally not implemented. This prevents unintended usage of Result<T> where T might be handled by RequestContext::handle or RequestContext::handle_async, avoiding subtle bugs.
• For JSON-RPC errors received from a server, see SessionError.
