Enum SyncError 

pub enum SyncError {
    Io(Error),
    UnknownPeer,
    IndexOutOfRange,
    EncodingError(String),
    CursorMismatch {
        expected_idx: u64,
        actual_idx: u64,
    },
    CodecError(CodecError),
    Backend(Box<dyn Error + Send + Sync>),
}

The sync subsystem’s error: reading a log (LogSource), applying entries (LogProcessor), or writing the local log (FileLogSink). Backends erase their own errors into SyncError::Backend, so the object-safe traits share one fixed error type instead of an associated one.

Variants

Io(Error)

An underlying I/O error.

UnknownPeer

A peer id that this source/sink does not know.

IndexOutOfRange

A requested entry index lay outside the peer’s log.

EncodingError(String)

A value could not be encoded for transport/storage.

CursorMismatch

The pull cursor’s expected next index disagreed with the source — the streams are out of sync.

Fields

expected_idx: u64

Entry index the cursor expected next.

actual_idx: u64

Entry index the source actually presented.

CodecError(CodecError)

A wire-format error decoding a peer’s log entries.

Backend(Box<dyn Error + Send + Sync>)

A backend failure erased behind a boxed error, letting a concrete replica surface its own error type through the fixed trait boundary.

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<CodecError> for SyncError

fn from(source: CodecError) -> Self

Converts to this type from the input type.

impl From<Error> for SyncError

fn from(source: Error) -> Self

Converts to this type from the input type.
