        diagnostic: Arc<Diagnostic>,
        statement: Option<String>,
    },
    Cancelled,
    Timeout,
    Disconnected,
}

Errors that can occur during streaming query execution.

Variants

Fields

diagnostic: Arc<Diagnostic>

Cancelled

Stream was cancelled via cancellation token.

Timeout

Implementations

impl StreamError

pub fn query_with_statement(err: Error, statement: String) -> StreamError

Create a query error with a statement context.

Trait Implementations

impl Clone for StreamError

fn clone(&self) -> StreamError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamError

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

Formats the value using the given formatter.

impl Display for StreamError

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

Formats the value using the given formatter.

impl Error for StreamError

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 StreamError

fn from(err: Error) -> StreamError

Converts to this type from the input type.
