Enum ClientError 

pub enum ClientError {
    NoReachableEndpoints,
    Transport(Error),
    TransportFanout(String),
    Rpc(Status),
    InvalidEndpoint(String),
    InvalidCount(u32),
    Connector(Box<dyn Error + Send + Sync + 'static>),
    DriverGone,
}

Variants

NoReachableEndpoints

Transport(Error)

TransportFanout(String)

A Self::Transport failure observed on one endpoint, fanned out to the sibling waiters of a coalesced request chunk. tonic::transport::Error is not Clone, so the originating value cannot be duplicated across waiters; this variant carries its Display text instead. Distinct from Self::NoReachableEndpoints: a single endpoint’s transport failed, not the whole cluster — collapsing the two would mislead tracing/alerting on the receiving side.

Rpc(Status)

InvalidEndpoint(String)

InvalidCount(u32)

Connector(Box<dyn Error + Send + Sync + 'static>)

DriverGone

Local driver task has terminated (typically a panic in the user-supplied RPC closure) and can no longer serve requests. Distinct from Self::NoReachableEndpoints: the network is fine, the in-process driver is dead. Operators should look for a panic in their tracing logs, not a network issue.

Trait Implementations

impl Debug for ClientError

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

Formats the value using the given formatter.

impl Display for ClientError

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

Formats the value using the given formatter.

impl Error for ClientError

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 ClientError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Status> for ClientError

fn from(source: Status) -> Self

Converts to this type from the input type.
