Variants

SuspendContainer

Suspends the container running in job.

The call will return successfully when wake_event has been signaled. Returns an error if wake_locks is signaled at the end of suspension, or an error is encountered when suspending the container’s processes.

Fields

payload: ManagerSuspendContainerRequest

responder: ManagerSuspendContainerResponder

ProxyWakeChannel

Creates a pass-through proxy that forwards messages between the container_channel and the remote_channel.

If any messages arrive on remote_channel while the container is suspended via SuspendContainer, the container will be resumed and counter will be incremented.

Once that message is handled by the container, and it’s ok to suspend the container again (relative to that message), the counter is expected to be decremented.

Fields

payload: ManagerProxyWakeChannelRequest

control_handle: ManagerControlHandle

AddWakeSource

Adds signals on handle as a way to prevent the container from suspending, or wake it if it is already suspended.

Fields

payload: ManagerAddWakeSourceRequest

control_handle: ManagerControlHandle

RemoveWakeSource

Removes a wake source handle from the container_job.

If the container is currently suspended, the handle may still wake the container if its signals are raised. To ensure that the wake source never wakes the container again after this call, the client must make sure that the signals are cleared and not raised again.

Fields

payload: ManagerRemoveWakeSourceRequest

control_handle: ManagerControlHandle

RegisterWakeWatcher

Registers an eventpair that will be signaled when the container is suspended or resumed. The signals are ASLEEP(USER_1) and AWAKE(USER_0).

The kernel returns AWAKE upon initial registration of the eventpair.

Fields

payload: ManagerRegisterWakeWatcherRequest

responder: ManagerRegisterWakeWatcherResponder

CreatePager

Creates a Pager instance with the provided backing_vmo and block_size.

Fields

payload: ManagerCreatePagerRequest

control_handle: ManagerControlHandle

_UnknownMethod

An interaction was received which does not match any known method.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

ordinal: u64

Ordinal of the method that was called.

control_handle: ManagerControlHandle

method_type: MethodType
