Struct couchdb::Nok

pub struct Nok {
    pub error: String,
    pub reason: String,
    // some fields omitted
}

Nok contains the content of an error response from the CouchDB server.

Summary

• Nok has public members instead of accessor methods because there are no invariants restricting the data.

• Nok implements Deserialize.

Remarks

When the CouchDB server responds with a 4xx- or 5xx status code, the response usually has a body containing a JSON object with an “error” string and a “reason” string. For example:

{
  "error": "file_exists",
  "reason": "The database could not be created, the file already exists."
}

The Nok type contains the information from the response body.

extern crate couchdb;
extern crate serde_json;

let nok: couchdb::Nok = serde_json::from_slice(body).unwrap();

assert_eq!(nok.error, "file_exists");
assert_eq!(nok.reason,
           "The database could not be created, the file already exists.");

Compatibility

Nok contains a dummy private member in order to prevent applications from directly constructing a Nok instance. This allows new fields to be added to Nok in future releases without it being a breaking change.

Fields

error: String

reason: String
