risingwave_stream::executor::exchange::error

Struct ExchangeChannelClosed

source 
pub struct ExchangeChannelClosed {
    message: String,
    source: Option<TonicStatusWrapper>,
}
Expand description

The error type for the exchange channel closed unexpectedly.

In most cases, this error happens when the upstream or downstream actor exits or panics on other errors, or the network connection is broken. Therefore, this error is usually not the root case of the failure in the streaming graph.

Fields§

§message: String§source: Option<TonicStatusWrapper>

Some if there is a gRPC error from the remote actor.

Implementations§

source§

impl ExchangeChannelClosed

source

pub fn local_input(upstream: ActorId) -> Self

Creates a new error indicating that the exchange channel from the local upstream actor is closed unexpectedly.

source

pub fn remote_input(upstream: ActorId, source: Option<Status>) -> Self

Creates a new error indicating that the exchange channel from the remote upstream actor is closed unexpectedly, with an optional gRPC error as the cause.

source

pub fn output(downstream: ActorId) -> Self

Creates a new error indicating that the exchange channel to the downstream actor is closed unexpectedly.
