Struct Heartbeat 

pub struct Heartbeat {
    pub socket: OsString,
    pub interval: Duration,
}

Where to send the heartbeat, and how often.

Fields

socket: OsString

The NOTIFY_SOCKET address: a filesystem path, or an abstract socket name that starts with @.

interval: Duration

Half the watchdog period, as sd_watchdog_enabled(3) recommends.

Implementations

impl Heartbeat

pub fn from_env_vars( notify_socket: Option<OsString>, watchdog_usec: Option<&str>, watchdog_pid: Option<&str>, own_pid: u32, ) -> Option<Self>

The heartbeat systemd asks for through the environment, or None when it asks for none.

WATCHDOG_PID, when set, names the process the watchdog is for. A process with another PID does not send the heartbeat.

pub fn from_env() -> Option<Self>

The heartbeat systemd asks this process for.
