A stable, non-exhaustive classification of failures.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedPlatform

The requested operating-system operation is unavailable on this target.

SessionLimit

All 64 Restart Manager session slots in the user session are occupied.

InvalidSessionKey

A session key was malformed, expired, or otherwise rejected.

Cancelled

A shutdown or restart operation was cancelled.

AccessDenied

Windows denied access to a resource or process.

InvalidInput

Input could not be represented by the native API.

DirectoryNotSupported

Restart Manager does not accept directories as file resources.

TooManyResources

A collection was too large for the native u32 count fields.

CallbackInUse

Another process-wide progress callback operation is active.

DataChanged

The affected-application or filter list changed through every retry.

MalformedOsData

Windows returned an internally inconsistent buffer.

RebootRequired

Windows requires a system reboot before this operation can proceed.

ShutdownIncomplete

At least one affected application could not be shut down.

RestartIncomplete

At least one stopped application could not be restarted.

OperationOutOfSequence

An operation was requested in an invalid native sequence.

RegistryUnavailable

Restart Manager could not access its registry state.

FilterNotFound

The selected filter does not exist.

OutOfMemory

The operating system could not allocate required memory.

ApplicationRestartInUse

This process already owns a crate-managed restart registration.

AsyncWorkerUnavailable

A dedicated asynchronous worker thread could not be created or failed.

SessionEnded

The weak cancellation capability refers to an ended session.

Os

Another Windows error not covered by a more specific classification.
