A [Matrix](https://matrix.org/) client library written in Rust.
|
|
|
|
The matrix-sdk aims to be a general purpose client library for writing Matrix
|
|
clients, bots, and other Matrix related things that use the client-server API to
|
|
communicate with a Matrix homeserver.
|
|
|
|
# Examples
|
|
Connecting and logging in to a homeserver is pretty starightforward:
|
|
|
|
```rust,no_run
|
|
use std::convert::TryFrom;
|
|
use matrix_sdk::{
|
|
Client, SyncSettings, Result,
|
|
ruma::{UserId, events::{SyncMessageEvent, room::message::MessageEventContent}},
|
|
};
|
|
|
|
#[tokio::main]
|
|
async fn main() -> Result<()> {
|
|
let alice = UserId::try_from("@alice:example.org")?;
|
|
let client = Client::new_from_user_id(alice.clone()).await?;
|
|
|
|
// First we need to log in.
|
|
client.login(alice.localpart(), "password", None, None).await?;
|
|
|
|
client
|
|
.register_event_handler(
|
|
|ev: SyncMessageEvent<MessageEventContent>| async move {
|
|
println!("Received a message {:?}", ev);
|
|
},
|
|
)
|
|
.await;
|
|
|
|
// Syncing is important to synchronize the client state with the server.
|
|
// This method will never return.
|
|
client.sync(SyncSettings::default()).await;
|
|
|
|
Ok(())
|
|
}
|
|
```

# Crate Feature Flags
|
|
|
|
The following crate feature flags are available:
|
|
|
|
* `encryption`: Enables end-to-end encryption support in the library.
|
|
* `sled_cryptostore`: Enables a Sled based store for the encryption keys. If
|
|
this is disabled and `encryption` support is enabled the keys will by
|
|
default be stored only in memory and thus lost after the client is
|
|
destroyed.
|
|
* `markdown`: Support for sending markdown formatted messages.
|
|
* `socks`: Enables SOCKS support in reqwest, the default HTTP client.
|
|
* `sso_login`: Enables SSO login with a local http server.
|
|
* `require_auth_for_profile_requests`: Whether to send the access token in
|
|
the authentication header when calling endpoints that retrieve profile
|
|
data. This matches the synapse configuration
|
|
`require_auth_for_profile_requests`. Enabled by default.
|
|
* `appservice`: Enables low-level appservice functionality. For an
|
|
high-level API there's the `matrix-sdk-appservice` crate
|
|
* `anyhow`: Support for returning `anyhow::Result<()>` from event handlers.
|

# Enabling logging
|
|
|
|
Users of the matrix-sdk crate can enable log output by depending on the
|
|
`tracing-subscriber` crate and including the following line in their
|
|
application (e.g. at the start of `main`):
|
|
|
|
```rust
|
|
tracing_subscriber::fmt::init();
|
|
```
|
|
|
|
The log output is controlled via the `RUST_LOG` environment variable by
|
|
setting it to one of the `error`, `warn`, `info`, `debug` or `trace` levels.
|
|
The output is printed to stdout.
|
|
|
|
The `RUST_LOG` variable also supports a more advanced syntax for filtering
|
|
log output more precisely, for instance with crate-level granularity. For
|
|
more information on this, check out the [tracing_subscriber documentation].
