test.TestServer.daemon_state

Module: test
Declared in: TestServer
Package: libtmux
Source: crates/libtmux/src/test.rs

daemon_state ( mut ) → DaemonState method [source] ¶ method [source] ¶ daemon_state

Report whether the daemon is still running, and how it ended if not.

Takes &mut self because reading the fate of a daemon that has exited reaps it; the guard then skips the signalling it no longer needs and still sweeps the panes the daemon left behind. Calling this on a running daemon changes nothing and costs one waitpid.

Examples

use std::time::Duration;

use libtmux::{Command, test::{DaemonState, TestServer, retry_until}};

let mut guard = TestServer::new().await?;
guard.session("work").await?;
guard.server().cmd(Command::new("kill-server")).await.ok();

// tmux stops answering on the socket before the kernel has a status
// for the process behind it, so this is a wait rather than a reading.
retry_until(Duration::from_secs(5), async || {
    !guard.daemon_state().is_running()
})
.await?;
assert!(matches!(guard.daemon_state(), DaemonState::Gone(_)));

guard.shutdown().await?;
