$sel:onInput:State', state_onInput - When an input is received and the condition is TRUE, perform the specified actions.

$sel:stateName:State', state_stateName - The name of the state.

state_onEnter :: Lens' State (Maybe OnEnterLifecycle)

When entering this state, perform these actions if the condition is TRUE.

state_onExit :: Lens' State (Maybe OnExitLifecycle)
