Enum SessionError 

pub enum SessionError {
    Io(Error),
    Chain(ChainError),
    Anchor(AnchorError),
    Relay(RelayError),
    Checkpoint(CheckpointError),
    MissingCheckpoint {
        checkpoint_hash: String,
    },
    CheckpointRegression {
        held: String,
        offered: String,
    },
    Lease(LeaseError),
}

A sync-session failure.

Variants

Io(Error)

Chain(ChainError)

Anchor(AnchorError)

Relay(RelayError)

Checkpoint(CheckpointError)

MissingCheckpoint

The journal carries a truncation marker naming a checkpoint that is not present in the session’s checkpoint directory — resume is impossible without it (fetch it from the relay and retry).

Fields

checkpoint_hash: String

CheckpointRegression

The relay served a “latest” checkpoint that does not cover the session’s current base — rebasing onto it would silently lose state.

Fields

held: String

offered: String

Lease(LeaseError)

A lease-coordinator call failed (B5) — used by the best-effort local gate SyncSession::record_intent_if_current.

Trait Implementations

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

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.
