Struct tarantool_module::error::TarantoolError

pub struct TarantoolError { /* fields omitted */ }

Implementations

impl TarantoolError

pub fn maybe_last() -> Result<(), Self>

Tries to get the information about the last API call error. If error was not set returns Ok(())

pub fn last() -> Self

Get the information about the last API call error.

The Tarantool error handling works most like libc's errno. All API calls return -1 or NULL in the event of error. An internal pointer to box_error_t type is set by API functions to indicate what went wrong. This value is only significant if API call failed (returned -1 or NULL).

Successful function can also touch the last error in some cases. You don't have to clear the last error before calling API functions. The returned object is valid only until next call to any API function.

You must set the last error using set_error() in your stored C procedures if you want to return a custom error message. You can re-throw the last API error to IPROTO client by keeping the current value and returning -1 to Tarantool from your stored procedure.

pub fn error_code(&self) -> TarantoolErrorCode

Return IPROTO error code

pub fn error_type(&self) -> String

Return the error type, e.g. "ClientError", "SocketError", etc.
