Module elastic::error

Client-side error types.

The main Error type combines the various kinds of errors that can occur when interacting with Elasticsearch. These include:

• Api: an error directly from an Elasticsearch exception, like index_not_found. This is the probably the variant you'll be interested in handling.
• Json: a general error serialising or deserialising json.
• Http: a general error in the http transport.

Examples

Any method defined in elastic that could fail will return a Result<T, Error> that can be matched on. The below example sends a request and then checks the response for an ErrorKind::Api:

// Send a request.
// This will return a Result<ResponseBuilder, Error>
let res = client.request(req)
                .send();

match res {
    Ok(response) => {
        // do something with the response
    },
    Err(e) => {
        match *e.kind() {
            ErrorKind::Api(ref e) => {
                // handle a REST API error
            },
            ref e => {
                // handle a HTTP or JSON error
            }
        }
    }
}
