Seshat is a database and indexer for Matrix events.
Its main use is to be used as a full text search backend for Matrix clients.
Seshat provides JavaScript bindings which can be found in the seshat-node subdir.
There are two modes of operation for Seshat, adding live events as they come in:
```rust use seshat::{Database, Event, Profile}; use tempfile::tempdir;
let tmpdir = tempdir().unwrap(); let mut db = Database::new(tmpdir.path()).unwrap();
/// Method to call for every live event that gets received during a sync. fn addliveevent(event: Event, profile: Profile, database: &Database) { database.addevent(event, profile); } /// Method to call on every successful sync after live events were added. fn onsync(database: &mut Database) { database.commit().unwrap(); } ```
The other mode is to add events from the room history using the
/room/{room_id}/messages Matrix API endpoint. This method supports
storing checkpoints which remember the arguments to continue fetching events
from the /room/{room_id}/messages API:
database.add_historic_events(events, old_checkpoint, new_checkpoint)?;
Once events have been added a search can be done:
let result = database.search("test", &SearchConfig::new()).unwrap();
