Struct PaverSynchronousProxy 

pub struct PaverSynchronousProxy { /* private fields */ }

Implementations

impl PaverSynchronousProxy

pub fn new(channel: Channel) -> Self

pub fn into_channel(self) -> Channel

pub fn wait_for_event( &self, deadline: MonotonicInstant, ) -> Result<PaverEvent, 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 find_data_sink( &self, data_sink: ServerEnd<DataSinkMarker>, ) -> Result<(), Error>

Attempts to auto-discover the data sink where assets and volumes will get paved to. On devices with GPT, the partition must have a valid FVM partition in order for auto-discovery to find it. If multiple devices are found suitable, error is returned.

data_sink will be closed on error, with an epitaph provided on failure reason.

pub fn open_partition_io( &self, block_dir: ClientEnd<DirectoryMarker>, partition_io: ServerEnd<PartitionIoMarker>, ) -> Result<(), Error>

Opens a PartitionIo session backed by block devices in the caller-provided block_dir.

Under the capability-delegated permission model, the paver component does not hold ambient access to all system block partitions. Instead, the caller (such as system-updater or fastboot) is responsible for routing the required block device capabilities into its own namespace (for example, via a scoped /block or /block/ota directory exposed by fshost) and passing block_dir to the paver for the duration of the PartitionIo session.

block_dir is expected to follow the fshost /block directory layout (see https://fuchsia.dev/fuchsia-src/development/storage/storage-partition-routing): each entry <entry>/ is a subdirectory containing a fuchsia.storage.block.Block protocol node at <entry>/fuchsia.storage.block.Block.

partition_io will be closed on error, with an epitaph provided on failure reason.

pub fn find_partition_table_manager( &self, data_sink: ServerEnd<DynamicDataSinkMarker>, ) -> Result<(), Error>

Like FindDataSink, but the returned block device will be dynamic, supporting partition table manipulation.

data_sink will be closed on error, with an epitaph provided on failure reason.

pub fn find_boot_manager( &self, boot_manager: ServerEnd<BootManagerMarker>, ) -> Result<(), Error>

Attempts to auto-discover the boot manager.

boot_manager will be closed on error, with an epitaph provided on failure reason. ZX_ERR_NOT_SUPPORTED indicates lack of support and configuration A is always booted from.

pub fn find_sysconfig( &self, sysconfig: ServerEnd<SysconfigMarker>, ) -> Result<(), Error>

Find Sysconfig service.
