Enum DriverError 

pub enum DriverError {
    Io(Error),
    Refused(Refusal),
    Protocol(ProtocolError),
    BackendClosed {
        reason: Option<ShutdownReason>,
        waiting: &'static str,
    },
    Timeout {
        waiting: &'static str,
        last_generation: u64,
        last_state: String,
    },
    Client(ClientError),
    Transport(String),
}

How the driver failed. Refusals and protocol errors are typed data, never strings parsed out of a stream.

Fields

reason: Option<ShutdownReason>

waiting: &'static str

Timeout

Fields

waiting: &'static str

last_generation: u64

last_state: String

The cached semantic state at expiry — a barrier failure must show what the backend actually published.

Trait Implementations

impl Debug for DriverError

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

Formats the value using the given formatter.

impl Display for DriverError

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

Formats the value using the given formatter.

impl Error for DriverError

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<ClientError> for DriverError

fn from(source: ClientError) -> Self

Converts to this type from the input type.

impl From<Error> for DriverError

fn from(source: Error) -> Self

Converts to this type from the input type.
