Struct StubPolicyEngine

pub struct StubPolicyEngine<P: Plan, T: TimeSource> { /* private fields */ }

A stub PolicyEngine that just gathers the current time and hands it off to the StubPolicy as the PolicyData.

impl<P: Debug + Plan, T: Debug + TimeSource> Debug for StubPolicyEngine<P, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

where T: TimeSource + Clone, P: Plan,

type TimeSource = T

type InstallResult = ()

type InstallPlan = P

fn time_source(&self) -> &Self::TimeSource

Provides the time source used by the PolicyEngine to the state machine.

fn compute_next_update_time( &mut self, apps: &[App], scheduling: &UpdateCheckSchedule, protocol_state: &ProtocolState, ) -> BoxFuture<'_, CheckTiming>

When should the next update happen?

fn update_check_allowed( &mut self, apps: &[App], scheduling: &UpdateCheckSchedule, protocol_state: &ProtocolState, check_options: &CheckOptions, ) -> BoxFuture<'_, CheckDecision>

Given the context provided by State, does the Policy allow an update check to happen at this time? This should be consistent with the compute_next_update_time so that during background updates, the result of compute_next_update_time will result in a CheckDecision::Ok() value from this function.

fn update_can_start<'p>( &mut self, proposed_install_plan: &'p Self::InstallPlan, ) -> BoxFuture<'p, UpdateDecision>

Given the current State, the current PolicyData, can the proposed InstallPlan be executed at this time.

fn reboot_allowed( &mut self, check_options: &CheckOptions, _install_result: &Self::InstallResult, ) -> BoxFuture<'_, bool>

Is reboot allowed right now.

fn reboot_needed( &mut self, install_plan: &Self::InstallPlan, ) -> BoxFuture<'_, bool>

Given the InstallPlan, is reboot needed after update has been installed.
