Enum BackendConnectionError 

pub enum BackendConnectionError {
    NotFound(ObjectKind),
    MaxConnectionRetries(Option<String>),
    MaxSessionsMemory,
    Backend(BackendError),
    RetrieveClusterError(RetrieveClusterError),
    MaxBuffers,
    TooManyConnectionsPerIp {
        cluster_id: String,
    },
}

Variants

NotFound(ObjectKind)

MaxConnectionRetries(Option<String>)

MaxSessionsMemory

Backend(BackendError)

RetrieveClusterError(RetrieveClusterError)

MaxBuffers

TooManyConnectionsPerIp

Per-(cluster, source-IP) connection limit reached. The protocol layer translates this into HTTP 429 Too Many Requests (with an optional Retry-After) for HTTP/HTTPS sessions, or a graceful TCP close for raw TCP. The cluster_id is included so log/metric pipelines can attribute the rejection.

Fields

cluster_id: String

Trait Implementations

impl Debug for BackendConnectionError

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

Formats the value using the given formatter.

impl Display for BackendConnectionError

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

Formats the value using the given formatter.

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.
