Rust client runtime

Enable silicon-dm-client's runtime feature for what the dm CLI does: Silicon Accounts sign-ins kept per profile, the durable outgoing relay, and the sync inbox. Build the standalone relay with cargo build -p silicon-dm-client --features runtime --bin dm-relay.

Signing a profile in

use silicon_dm_client::runtime::{DaemonCommand, LocalRuntime, ServiceCheck, SignInTarget};
let runtime = LocalRuntime::from_environment()?;           // or LocalRuntime::new(private_dir)
let target = SignInTarget::new(
    "assistant",                                           // profile
    "https://api.dm.teamofsilicons.com",               // DM API
    "https://accounts.teamofsilicons.com",                 // Silicon Accounts
    "dm",                                                  // app id
)?;
if let ServiceCheck::Unreachable(why) = LocalRuntime::check_service(&target).await? {
    eprintln!("could not check the DM service first: {why}");
}
let session = runtime.public_client(&target)?.exchange_slt(slt).await?;  // or the device flow
let status = runtime.save_sign_in(&target, &session, "slt", &DaemonCommand::default()).await?;
let verified = runtime.login_status("assistant").await?;
  • check_service asks the DM service (GET /api/v1/accounts) which Silicon Accounts and app id it trusts and refuses a mismatch before a single-use code or token is spent.
  • save_sign_in stores the session in the profile and starts the relay (a relay that cannot start is reported in the result; the sign-in is kept). A profile with queued requests from another account is never taken over (profile_in_use); the replaced sign-in of the same profile is revoked. A profile from before Silicon Accounts releases its queued requests only to the same public id and fails them (account_changed) otherwise.
  • login_status refreshes when needed and confirms with GET /api/v1/me; runtime::offline_status(profile) reads only the file, creates nothing and needs no home.
  • logout(profile) revokes the refresh token at Silicon Accounts and forgets the tokens; refresh(profile) refreshes now; profiles() lists every profile without secrets.

Errors that concern the sign-in are store::SessionError { code, message, hint } (not_signed_in, sign_in_ended, sign_in_required, profile_in_use, accounts_mismatch, app_id_mismatch, service_not_accounts) or accounts::SignInError.

Storage and refresh

from_environment() uses SILICON_DM_HOME, else the directory set with dm config home, else $SILICON_HOME/.silicon-dm, else $HOME/.silicon-dm. The directory is 0700, config.json is 0600 and replaced atomically under config.lock; symbolic links are refused. A file that cannot be read is kept as config.json.unreadable-<time> and replaced by defaults.

store().fresh_profile(key) returns the profile with at least a minute of access token left. When it must refresh, it takes refresh-<profile>.lock, re-reads the file (another process may have refreshed already), rotates the refresh token with Silicon Accounts and stores the new pair before returning it, so concurrent processes rotate once. A refused refresh token signs the profile out with the reason; a passing Silicon Accounts failure keeps using a token that still has more than 10 seconds left. with_client(profile, |client| …) runs a call with a fresh client and repeats it once after a 401 (nothing ran).

The outgoing relay

use silicon_dm_client::relay::{Operation, RelayRequest};
use silicon_dm_client::runtime::{DaemonCommand, LocalRuntime};
let request = RelayRequest::new("assistant", Operation::Me);
let starter = DaemonCommand { executable: "dm".into(), arguments: vec!["daemon".into(), "start".into()] };
let ack = runtime.submit_or_queue(&request, &starter).await?;   // durable before it returns
let relay = runtime.client()?;
let result = relay.result(ack.request_id).await?;

run() hosts the relay in this process (one per operating-system user; it refuses to start twice), start()/start_with() attaches this home to the running relay or launches one. The relay guide describes lanes, retries, the loopback API and upgrades.

The inbox

use silicon_dm_client::runtime::{InboxOptions, InboxStart, LocalRuntime};
let options = InboxOptions {
    profile: "assistant".into(),
    watch: true,
    wait: 30,
    start: InboxStart::Saved,
    hydrate: true,
    mark_delivered: false,
    limit: None,
    conversations: true,
};
runtime
    .inbox(&options, |line| { println!("{line}"); Ok(()) }, |notice| eprintln!("{notice}"))
    .await?;

inbox long-polls GET /api/v1/sync, emits one JSON value per event (with the current message when hydrate; with conversations, also a conversation value when a conversation appears, changes or goes away for the account), a cursor value after each batch, and saves the cursor per profile after every page. Without watch it returns a done value once nothing is pending. Passing failures are retried with a growing pause and reported through the second callback; a sync_reset_required answer emits a reset value and continues from a fresh cursor. sync_page(profile, &request) reads one page instead. Receive messages documents every line.
