Struct persist::error::ErrorLog

pub struct ErrorLog;

A stub implementation of Log that always returns errors.

This exists to let us keep the (surprisingly non-trivial) Log plumbing while we don’t actually use it, but without the risk of accidentally using it.

Trait Implementations

impl Debug for ErrorLog

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

Formats the value using the given formatter.

impl Log for ErrorLog

fn write_sync(&mut self, _buf: Vec<u8>) -> Result<SeqNo, Error>

Synchronously appends an entry.

fn snapshot<F>(&self, _logic: F) -> Result<Range<SeqNo>, Error> where
    F: FnMut(SeqNo, &[u8]) -> Result<(), Error>, 

Returns a consistent snapshot of all written but not yet truncated entries.

fn truncate(&mut self, _upper: SeqNo) -> Result<(), Error>

Removes all entries with a SeqNo strictly less than the given upper bound.

fn close(&mut self) -> Result<bool, Error>

Synchronously closes the log, releasing exclusive-writer locks and causing all future commands to error.
