Enum TransportError 

pub enum TransportError {
    NoApp,
    Remote(RpcError),
    Transport(String),
}

Failure talking to the live app over the socket, in three semantic classes that mirror scrybe_rpc::ClientError’s taxonomy.

Variants

NoApp

No Scrybe app is running to service the request (scrybe_rpc::ClientError::is_not_running). A business condition — tools report it as the no_live_app tool_error.

Remote(RpcError)

The app ANSWERED with an in-band JSON-RPC error object. The transport worked; this is a business outcome (tools report it as app_error).

Transport(String)

The transport itself failed: socket I/O, timeouts, frame/UTF-8/JSON problems, or an envelope violation. The app did not answer — dispatch maps this to EngineFault::Transport, never to a business outcome.

Trait Implementations

impl Debug for TransportError

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

Formats the value using the given formatter.

impl Display for TransportError

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

Formats the value using the given formatter.

impl Error for TransportError

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.
