Struct RelayError 

pub struct RelayError {
    pub msg_id: u64,
    pub error: Arc<dyn Error + Send + Sync>,
    pub source: &'static str,
}

Error from a downstream handler in the stream.

Errors are cloneable (via Arc) and can flow both:

• Through the stream (subscribable via subscribe::<RelayError>())
• Back to senders (via send().await returning Err(SendError::Downstream(...)))

Fields

msg_id: u64

The message ID that caused this error (0 if unknown).

error: Arc<dyn Error + Send + Sync>

The underlying error.

source: &'static str

Coarse provenance indicator for the error source.

This should be a compile-time constant string like “sink”, “tap”, “within”, “subscription”, or “forwarder”. Not intended for user input.

Implementations

impl RelayError

pub fn new<E: Error + Send + Sync + 'static>( msg_id: u64, error: E, source: &'static str, ) -> Self

Create a new RelayError.

Trait Implementations

impl Clone for RelayError

fn clone(&self) -> RelayError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelayError

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

Formats the value using the given formatter.

impl Display for RelayError

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

Formats the value using the given formatter.

impl Error for RelayError

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.
