Struct AppendOnlyLog 

pub struct AppendOnlyLog { /* private fields */ }

A lock-free append-only log for high-throughput message storage

Design goals:

• Lock-free appends from multiple producers
• Sequential reads optimized for batching
• Memory-efficient with segment rotation

Implementations

impl AppendOnlyLog

pub fn new(config: AppendLogConfig) -> Self

Create a new append-only log

pub fn append(&self, data: &[u8]) -> u64

Append data to the log, returns the offset

pub fn append_batch(&self, entries: &[&[u8]]) -> Vec<u64>

Append a batch of entries, returns vec of offsets

pub fn read(&self, start_offset: u64, max_entries: usize) -> Vec<Bytes>

Read entries starting from an offset

pub fn total_bytes(&self) -> u64

Get total bytes written

pub fn total_entries(&self) -> u64

Get total entries written

pub fn end_offset(&self) -> u64

Get current end offset

pub fn segment_count(&self) -> usize

Get number of segments
