Crate acyclic_native_runtime

Expand description

Private native file primitives shared by durable local providers.

Structs§

AsyncRangeReader: Bounded asynchronous positional source backed by the native completion path.
BlockingIoTask: Runtime-independent bounded offload for host operations without a native completion path, such as file locks and directory namespace transactions. Dropping the observer after admission does not cancel the operation.
NativeCompletion: Runtime-independent completion of an owned native-file operation. Once admitted, dropping the observer never cancels the underlying operation.
NativeFile: One file owned by the native I/O runtime.
OwnedRead: One owned positional read request.
OwnedWrite: One owned positional write whose buffer remains live through completion.
OwnershipAnchor: Shared lifetime token for native resources that must not outlive an external owner.
OwnershipReleaseBarrier: A non-owning release condition for an OwnershipAnchor clone family.
ProcessTree: One child and descendants that remain in its operating-system containment.
RangeReader: Bounded positional source for one file range.

durable_rename: Renames one filesystem entry and durably publishes the affected namespace.
is_exclusive_lock_contention: Whether an exclusive file-lock failure proves that another owner holds the lock. Other failures must retain their original I/O error for recovery decisions.
is_uncertain_io_error: Whether a native operation may still have an unresolved kernel completion.
read_at: Reads at an absolute offset without changing the file cursor.
read_batch_async: Submits an owned read batch to the shared native completion worker.
run_blocking_io: Schedules one owned host operation on the bounded native worker pool. Creating the future is lazy; polling it admits the operation.
spawn_process_tree: Starts a child in an owned operating-system process tree.
spawn_service_process: Starts the current executable’s __service mode without inheriting host standard-I/O handles.
sync_data: Flushes file data according to durability.
sync_file: Flushes file contents and metadata according to durability.
sync_parent: Flushes the directory entry namespace on platforms exposing directory flushes.
write_all_at: Writes every byte at an absolute offset without changing the file cursor.
write_all_batch_async: Submits an owned write batch to the shared native completion workers.

ReadBatch: Completion of one owned native read batch.
UnitCompletion: Completion of an owned write, resize, sync, or file-control operation.
