SyncSession

coven::sync::session

Struct SyncSession 

Source 
pub struct SyncSession { /* private fields */ }
Expand description

A sync session that tracks changes to all synced tables on a single connection.

Lifecycle:

  1. SyncSession::start(db) – creates and attaches
  2. App writes normally through the connection
  3. session.changeset() – grabs the binary diff (None if no changes)
  4. Session is dropped (or explicitly ended by dropping)

The session must be dropped before applying incoming changesets to avoid contaminating the next outgoing changeset with other devices’ changes.

Implementations§

Source§

impl SyncSession

Source

pub unsafe fn start(db: *mut sqlite3) -> Result<Self, SyncError>

Create a new sync session on the given raw sqlite3 connection, attaching all synced tables.

§Safety

db must be a valid, open sqlite3 connection pointer. The session must be dropped before the connection is closed.

Source

pub fn changeset(&self) -> Result<Option<Changeset>, SyncError>

Grab the binary changeset of all changes since the session started. Returns None if no changes were made (avoids pushing empty changesets).
