Struct MemoryOperationLog 

pub struct MemoryOperationLog { /* private fields */ }

In-memory operation log (for testing/development) For production, implement FileOperationLog or DatabaseOperationLog

Implementations

impl MemoryOperationLog

pub fn new() -> Self

pub fn append(&self, operation: Operation) -> Result<u64, String>

Append an operation to the log Returns the log index assigned to this operation

pub fn get_by_id(&self, operation_id: &OperationId) -> Option<OperationLogEntry>

Get an operation by its ID

pub fn get_by_index(&self, log_index: u64) -> Option<OperationLogEntry>

Get an operation by log index

pub fn get_range( &self, start_index: u64, end_index: u64, ) -> Vec<OperationLogEntry>

Get all operations in range [start_index, end_index)

pub fn size(&self) -> u64

Get the current size of the log (number of entries)

pub fn iter(&self) -> Vec<OperationLogEntry>

Iterate over all entries in the log

pub fn contains_operation_id(&self, operation_id: &OperationId) -> bool

Check if an operation ID has been logged

pub fn truncate(&self, truncate_at: u64) -> Result<(), String>

Truncate the log at the given index (for recovery/compaction) Keeps entries with log_index < truncate_at
