session_manager_lib::power

Struct PowerElement

Source 
pub struct PowerElement { /* private fields */ }
Expand description

A power element representing the session.

This power element is owned and registered by session_manager. This power element is added in the power topology as a dependent on the Application Activity element that is owned by the SAG.

After session_manager starts, a power-on lease will be created and retained. The session component may fetch the lease from session_manager and decide when to drop it.

When stopping or restarting the session, the power element and the power-on lease will be recreated, returning thing to the initial started state.

Implementations§
