Struct DurableLog 

pub struct DurableLog { /* private fields */ }

Append-only transaction log with synchronous commit durability.

Implementations

impl DurableLog

pub fn append_transaction( &mut self, transaction_id: Uuid, operations: &[Vec<u8>], ) -> Result<AppendOutcome, LogError>

Appends and synchronizes one atomic transaction.

Retrying the same identifier and operation bytes returns the original receipt without appending. Reusing it with different bytes fails.

Errors

Returns an error for invalid bounds, conflicting idempotency keys, or filesystem failures. Any append/sync failure poisons the writer so the caller must reopen and recover before another write.

Trait Implementations

impl Debug for DurableLog

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

Formats the value using the given formatter.
