Small rust library for the Matrix protocol
Right now, only the following are supported:
- joining rooms
- sending text messages and
- receiving text messages
Support for room creation and receiving other kinds of messages are planned for the near time. Also, image upload is on my personal to-do list. :)
First, add this to your Cargo.toml:
[dependencies]
dementia = "*"In order to connect to a Matrix homeserver and join a room, you need a user on that homeserver and an access token for that user.
let server_url = "https://matrix.org"; // The Matrix homeserver
let access_token = "DAx…3wo"; // The Matrix user access tokenWith that, you can create a Homeserver object
let connection = Homeserver::new(server_url)
.access_token(access_token)
.connect();or alternatively
let connection = MatrixHomeserver::connect(server_url, access_token);and use this object to join rooms:
let mut room = connection.join("#bottest:https://matrix.org".to_owned());(You need to join a room you want to interact with even if you are already joined. This is for the library to obtain the room id.)
You receive new messages with connection.get_new_messages() (which returns a Vector<String> of all messages since last called) and send messages with connection.send_message() (which takes a String).
extern crate dementia;
use dementia::{Homeserver, Room};
use std::{thread, time};
fn main() {
let server_url = "https://matrix.org"; // The Matrix homeserver
let access_token = "DAx…3wo"; // The Matrix user access token
let conn = Homeserver::new(server_url)
.access_token(access_token)
.connect();
// The room must already exist
let mut room = conn.join("#bottest:https://matrix.org".to_owned());
let five_sec = time::Duration::new(5, 0);
loop {
for message in conn.get_new_messages() {
if message == "hi" {
conn.send_message("ahoi!".to_owned());
}
}
thread::sleep(five_sec);
}
}If you don't have an access token (yet) but the server supports password authentication, you can let the library generate its own access token:
let connection = Homeserver::new("https://matrix.org")
.username("@example:matrix.org")
.password("examplepassword")
.login()
.connect();Subsequentlty, you can retrieve the access token for future connections using
access_token = connection.get_access_token();
