Provides access to the minimal API exposed by a kernel.

Safety

See the Safety section of the module documentation.

Associated Types

type RawDebugPrinter: Debug + Send + Sync

type RawTaskId: Id

The type to identify tasks.

Associated Constants

const RAW_SUPPORTED_QUEUE_ORDERS: &'static [Option<QueueOrderKind>]

Used by QueueOrder::is_supported.

None elements don’t match any values of QueueOrder. This might be useful for conditionally enabling some of them.

The default value is an empty slice.
