Enum TransportError 

pub enum TransportError {
    Unavailable(String),
    Unauthorized(String),
    Protocol(String),
    FrontierTruncated {
        device_id: String,
        dropped_below: u64,
    },
}

A transport-level failure — the service was unreachable or misbehaved. Distinct from an in-band verdict (a deduped push, a Held lease): those are success returns, not errors.

Variants

Unavailable(String)

The service could not be reached / timed out / returned a transport error (HTTP 5xx, connection reset, …).

Unauthorized(String)

The caller is not authorized for scope (bad/expired Parslee token).

Protocol(String)

A reply could not be parsed into the expected shape (protocol drift).

FrontierTruncated

A pull requested a frontier below the relay’s GC floor for device_id (retained ops start at dropped_below). NOT a failure — the service’s signal that the caller must cold-bootstrap from the latest checkpoint. Maps to RelayError::FrontierTruncated, which crate::session::SyncSession::pump already handles by rebasing.

Fields

device_id: String

dropped_below: u64

Trait Implementations

impl Clone for TransportError

fn clone(&self) -> TransportError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TransportError

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.

impl From<TransportError> for RelayError

fn from(e: TransportError) -> Self

Converts to this type from the input type.

impl PartialEq for TransportError

fn eq(&self, other: &TransportError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
