Struct scylla::transport::errors::BrokenConnectionError

pub struct BrokenConnectionError(/* private fields */);

An error indicating that a connection was broken. Possible error reasons:

• keepalive query errors - driver failed to sent a keepalive query, or the query timed out
• received a frame with unexpected stream id
• failed to handle a server event (message received on stream -1)
• some low-level IO errors - e.g. driver failed to write data via socket

Implementations

impl BrokenConnectionError

pub fn downcast_ref<T: Error + 'static>(&self) -> Option<&T>

Retrieve an error reason by downcasting to specific type.

Trait Implementations

impl Clone for BrokenConnectionError

fn clone(&self) -> BrokenConnectionError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BrokenConnectionError

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

Formats the value using the given formatter.

impl Display for BrokenConnectionError

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

Formats the value using the given formatter.

impl Error for BrokenConnectionError

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

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.
