Struct SyncState 

pub struct SyncState {
    pub session_id: String,
    pub last_processed_index: Option<usize>,
    pub last_soul_hash: String,
    pub last_sync_timestamp: DateTime<Utc>,
    pub last_hot_cache_count: usize,
    pub last_hot_cache_hash: String,
}

Incremental sync position for a single session.

Fields

session_id: String

Session identifier (matches .nexus/sessions/{session_id}/).

last_processed_index: Option<usize>

Index of the last-processed transcript entry (None = never synced).

last_soul_hash: String

Hash of the last soul.md content seen (detects dream/soul updates).

last_sync_timestamp: DateTime<Utc>

Timestamp of the last successful sync.

last_hot_cache_count: usize

Number of hot-cache entries at last sync (detects cache promotions).

last_hot_cache_hash: String

Hash of the hot cache entries at last sync (detects cache content changes).

Implementations

impl SyncState

pub fn load(project_root: &Path, session_id: &str) -> Result<Self>

Load sync state for a session, creating a fresh one if none exists.

pub fn save(&self, project_root: &Path) -> Result<()>

Persist the current sync state to disk.

pub fn new(session_id: &str) -> Self

Create a fresh sync state for a new session.

pub fn has_updates( &self, current_soul_hash: &str, current_hot_count: usize, current_hot_hash: &str, ) -> bool

Whether there are updates since the last sync (soul changed or cache changed).

pub fn advance( &mut self, soul_hash: String, hot_cache_count: usize, hot_cache_hash: String, new_index: Option<usize>, )

Record a successful sync, advancing all watermarks.
