Enum LoopError 

pub enum LoopError {
    Source(SourceError),
    Sink(SinkError),
    Encode(Error),
    Listen(BridgeError),
}

Why the loop stopped.

Variants

Source(SourceError)

The downstream peer stopped being readable.

A refused envelope is not here. Those are answered and counted in LoopReport::failed; only the pipe itself failing ends the loop.

Sink(SinkError)

A reply did not reach the downstream peer.

Encode(Error)

An envelope the bridge itself built could not be written as text.

Every value this loop serialises came out of JSON that already parsed, so it cannot happen — but the signature says it can, and an expect here would be a panic on the proxy’s own output rather than on a peer’s bytes, which is the one place a panic is least defensible.

Listen(BridgeError)

The upstream peer’s out-of-band channel could not be opened.

Its own variant because it is the one failure here that says nothing about the downstream pipe: every request already relayed still works, so a caller that wanted a degraded bridge can carry on, and one that did not now has the name of the thing that broke.

Trait Implementations

impl Debug for LoopError

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

Formats the value using the given formatter.

impl Display for LoopError

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

Formats the value using the given formatter.

impl Error for LoopError

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
