pub struct DataSinkProxy { /* private fields */ }

Implementations§

source§

impl DataSinkProxy

source

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.paver/DataSink.

source

pub fn take_event_stream(&self) -> DataSinkEventStream

Get a Stream of events from the remote end of the protocol.

§Panics

Panics if the event stream was already taken.

source

pub fn read_asset( &self, configuration: Configuration, asset: Asset ) -> QueryResponseFut<DataSinkReadAssetResult>

Reads partition corresponding to configuration and asset into a vmo and returns it.

source

pub fn write_asset( &self, configuration: Configuration, asset: Asset, payload: Buffer ) -> QueryResponseFut<i32>

Writes partition corresponding to configuration and asset with data from payload. payload may need to be resized to the partition size, so the provided vmo must have been created with ZX_VMO_RESIZABLE or must be a child VMO that was created with ZX_VMO_CHILD_RESIZABLE. Will zero out rest of the partition if payload is smaller than the size of the partition being written.

Returns ZX_ERR_INVALID_ARGS if configuration specifies active configuration.

source

pub fn write_firmware( &self, configuration: Configuration, type_: &str, payload: Buffer ) -> QueryResponseFut<WriteFirmwareResult>

Writes firmware data from payload.

configuration represents the A/B/R configuration. For platforms that do not support firmware A/B/R, the parameter will be ignored by the underlying device-specific logic .

type is a device-specific string identifying the payload contents, used to select the proper paving logic. For example, a device with multiple bootloader stages might send them as separate calls to WriteFirmware(), differentiated by type. An empty string indicates the default type.

payload may need to be resized to the partition size, so the provided vmo must have been created with ZX_VMO_RESIZABLE or must be a child VMO that was created with ZX_VMO_CHILD_RESIZABLE.

source

pub fn read_firmware( &self, configuration: Configuration, type_: &str ) -> QueryResponseFut<DataSinkReadFirmwareResult>

Read firmware corresponding to configuration and type.

Parameter configuration and type are the same as WriteFirmware.

If ReadFirmware returns error, caller should assume that firmware image does not exist or is in a bad state, or firmware read is not defined for the product.

source

pub fn write_volumes( &self, payload: ClientEnd<PayloadStreamMarker> ) -> QueryResponseFut<i32>

Writes FVM with data from streamed via payload. This potentially affects all configurations.

source

pub fn write_opaque_volume( &self, payload: Buffer ) -> QueryResponseFut<DataSinkWriteOpaqueVolumeResult>

Write a raw volume image to the device. The image will be passed as it is to the device partitioner backend to write. Therefore the format and write logic for the image is up to the product to define. It differs from WriteVolume(), which is specifically for writing the FVM sparse image, in that the paver will not perform any FVM related parsing or other operation of the image. Thus it is not dependent on the volume driver version and less susceptible to an outdated paver.

Returns ZX_ERR_NOT_SUPPORTED if the backend does not support opaque volume blobs.

source

pub fn write_sparse_volume( &self, payload: Buffer ) -> QueryResponseFut<DataSinkWriteSparseVolumeResult>

Writes an image in the Android Sparse format. Identical in behaviour to WriteOpaqueVolume, except the contents of payload are parsed as a sparse image and unpacked before being written to disk.

source

pub fn flush(&self) -> QueryResponseFut<i32>

Flush all previously buffered writes to persistent storage.
