Struct TankManager 

pub struct TankManager { /* private fields */ }

Ref-counted session manager: first acquire starts sim; last explicit release stops it immediately so topology nodes (tank / tank_viz) disappear.

Implementations

impl TankManager

pub fn new(endpoints: TankEndpoints) -> Arc<Self>

pub fn with_timing( endpoints: TankEndpoints, lease: Duration, stop_grace: Duration, ) -> Arc<Self>

pub fn lease(&self) -> Duration

pub fn acquire(&self) -> Result<TankSession>

pub fn heartbeat(&self, session_id: &str) -> Result<TankSession>

pub fn release(&self, session_id: &str) -> Result<TankStatus>

pub fn status(&self) -> TankStatus

pub fn shutdown(&self)

Force-stop the sim and drop all sessions (broker shutdown).
