Implementations

impl RecoverySynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<RecoveryEvent, Error>

Waits until an event arrives and returns it. It is safe for other threads to make concurrent requests while waiting for an event.

pub fn init_system_partition_table( &self, partitions: &[PartitionInfo], ___deadline: MonotonicInstant, ) -> Result<RecoveryInitSystemPartitionTableResult, Error>

Wipes and re-initializes the system partition table. This is a destructive operation!

pub fn write_data_file( &self, filename: &str, payload: Vmo, ___deadline: MonotonicInstant, ) -> Result<RecoveryWriteDataFileResult, Error>

Writes filename into the data partition with contents from payload, formatting the data partition if it isn’t already formatted. Overwrites file if it already exists.

This can only be called while the data partition isn’t already mounted, which is typically in recovery builds where fshost is running with the ramdisk_image flag set.

pub fn wipe_storage( &self, blobfs_root: Option<ServerEnd<DirectoryMarker>>, blob_creator: Option<ServerEnd<BlobCreatorMarker>>, ___deadline: MonotonicInstant, ) -> Result<RecoveryWipeStorageResult, Error>

Reprovision the first non-ramdisk FVM volume, and format/mount the blob partition. The formatted Blobfs instance can be accessed via the client end of blobfs_root; if no handle is provided, then blobfs won’t be formatted.

If fxblob is configured, blob_creator will be connected with the fxfs BlobCreator protocol, which should be used instead of creating blobs in the blobfs_root. blobfs_root will still be connected and can be used to read blobs. If fxblob is configured, but no handle is provided for blob_creator or for blobfs_root, the blob volume won’t be formatted. If a handle is provided for blob_creator but fxblob is not configured, the channel will be closed.

This function will pause the fshost block watcher regardless of success or failure. Requires fshost to be started with the ramdisk_image config option set to true.

WARNING: This will cause irreversible data loss. Use with caution.

TODO(https://fxbug.dev/42063480): This function unbinds all child drivers of the volume to be wiped. This can race with the fshost block device manager, which attempts to bind the FVM driver and unseal the zxcrypt volume.
