matrix-sdk-search

This crate implements a searchable index for messages in a Matrix client.

Usage

The recommended way to use this crate is to include matrix-sdk as a dependency in your Cargo.toml file with the experimental-search feature flag turned on.

Stand-alone usage

Constructing a matrix_sdk_search::index::RoomIndex is done with the matrix_sdk_search::index::builder::RoomIndexBuilder.

use std::path::PathBuf;
use matrix_sdk_search::{
    error::IndexError,
    index::{
        RoomIndex,
        builder::RoomIndexBuilder,
    },
};
use ruma::RoomId;

fn create_index(path: PathBuf, room_id: &RoomId) -> Result<RoomIndex, IndexError> {
    RoomIndexBuilder::new_on_disk(path, room_id).unencrypted().build()
}

The search crate accepts index operations through matrix_sdk_search::index::RoomIndex::execute() which takes a matrix_sdk_search::index::RoomIndexOperation.

use matrix_sdk_search::index::{
    RoomIndex, RoomIndexOperation,
    builder::RoomIndexBuilder
};
use ruma::events::room::message::OriginalSyncRoomMessageEvent;

async fn add_event(index: &mut RoomIndex, event: OriginalSyncRoomMessageEvent) {
    index.execute(RoomIndexOperation::Add(event));
}

Some method(s) for creating these operations will need to be implemented. There is an example of handling ruma::events::AnySyncTimelineEvents in matrix-sdk::search_index.
