Variants

Transport(Error)

Api

The service answered with a structured failure. Branch on code, not on the message.

Fields

status: u16

code: ErrorCode

response: ErrorResponse

UnknownCode

A structured failure with a code this client does not know, from a newer service.

Kept apart from Error::Unexpected because it is not a proxy getting in the way: the service answered, in its own shape, and the code and message are worth reading. Updating the client turns it into an Error::Api.

Fields

status: u16

code: String

message: String

question_id: Option<String>

Unexpected

A response that was not shaped like anything cerno sends — a proxy or a gateway between client and service, most likely. body is kept whole; the message shows its start, as the Python and TypeScript clients do, so a gateway’s HTML page does not fill a log line.

Fields

status: u16

body: String

MissingAnswer(String)

WrongType

Fields

id: String

expected: &'static str

actual: &'static str

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
