Enum SyncError 

pub enum SyncError {
    IdentityMismatch(String),
    ApplyInProgress(String),
    ApplyStateRequiresRepair(String),
    UntrustedApplyBoundary(String),
    InvalidRequest(String),
    CorruptState(String),
}

A refusal raised by the sync crate. See the module docs for the contract.

Variants

IdentityMismatch(String)

The replica’s sync identity does not descend from the history it was asked to apply. Resuming is impossible; the host must rebootstrap.

ApplyInProgress(String)

A stranded in-progress apply intent covers a different range than the caller’s, and the catalog LSN does not prove it void. Resume exactly from the recovered catalog boundary, or repair.

ApplyStateRequiresRepair(String)

The local apply state and the catalog disagree in a way no crash of a well-behaved apply produces. Manual repair required before retry.

UntrustedApplyBoundary(String)

The requested chunk start is not a boundary the local apply state vouches for. Re-derive the resume point from the catalog LSN.

InvalidRequest(String)

Catch-all for refusals of the caller’s request (io::ErrorKind::InvalidInput).

CorruptState(String)

Catch-all for on-disk or protocol state this crate refuses to trust (io::ErrorKind::InvalidData).

Trait Implementations

impl Debug for SyncError

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

Formats the value using the given formatter.

impl Display for SyncError

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

Formats the value using the given formatter.

impl Error for SyncError

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<SyncError> for Error

Source-preserving: the rendered text is unchanged (io::Error’s Display delegates to the payload) and the typed error stays recoverable via err.get_ref().and_then(|e| e.downcast_ref::<SyncError>()).

fn from(err: SyncError) -> Error

Converts to this type from the input type.
