Struct SymbolLogManager 

pub struct SymbolLogManager { /* private fields */ }

Symbol log writer/rotator that enforces append-only active-segment policy.

Implementations

impl SymbolLogManager

pub fn new( symbols_dir: &Path, active_segment_id: u64, epoch_id: u64, created_at: u64, ) -> Result<Self>

Open or create the active segment.

pub const fn active_segment_id(&self) -> u64

Current active segment identifier.

pub fn active_segment_path(&self) -> PathBuf

Filesystem path for the current active segment.

pub fn append(&self, record: &SymbolRecord) -> Result<SymbolLogOffset>

Append to the active segment.

pub fn append_to_segment( &self, segment_id: u64, record: &SymbolRecord, ) -> Result<SymbolLogOffset>

Append to a specific segment ID.

Rotated segments are immutable; only the active segment accepts writes.

pub fn rotate( &mut self, next_segment_id: u64, next_epoch_id: u64, next_created_at: u64, ) -> Result<()>

Rotate to a new active segment.
