Enum AppendSessionError 

#[non_exhaustive]
pub enum AppendSessionError {
    Append(AppendError),
    AckTimeout,
    ServerDisconnected,
    StreamClosedEarly,
    SessionClosed,
    SessionClosing,
    SessionDropped,
    InvalidAck(String),
}

Errors returned by an append session.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Append(AppendError)

An error with the append request underlying the session.

AckTimeout

An append acknowledgement timed out.

ServerDisconnected

The server disconnected during the session.

StreamClosedEarly

The response stream closed while appends were in flight.

SessionClosed

The session was already closed.

SessionClosing

The session is closing.

SessionDropped

The session was dropped without being closed.

InvalidAck(String)

The server returned an invalid append acknowledgement.

Implementations

impl AppendSessionError

pub fn is_retryable(&self) -> bool

Whether retrying the operation is safe or sensible.

pub fn has_no_side_effects(&self) -> bool

Whether retrying the operation cannot duplicate a mutation.

pub fn request_error(&self) -> Option<&RequestError>

Return the underlying request error, if present.

Trait Implementations

impl Clone for AppendSessionError

fn clone(&self) -> AppendSessionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AppendSessionError

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

Formats the value using the given formatter.

impl Display for AppendSessionError

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

Formats the value using the given formatter.

impl Error for AppendSessionError

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.
