Struct BlobCreatorProxy 

pub struct BlobCreatorProxy { /* private fields */ }

Implementations

impl BlobCreatorProxy

pub fn new(channel: AsyncChannel) -> Self

Create a new Proxy for fuchsia.fxfs/BlobCreator.

pub fn take_event_stream(&self) -> BlobCreatorEventStream

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

Panics

Panics if the event stream was already taken.

pub fn create( &self, hash: &[u8; 32], allow_existing: bool, ) -> QueryResponseFut<BlobCreatorCreateResult, DefaultFuchsiaResourceDialect>

Creates a blob with the merkle root hash. If allow_existing is true, the server will overwrite the existing blob if there is one. The server may fail this request with [CreateBlobError.ALREADY_EXISTS] if there is already an inflight BlobWriter for the same hash which has not been closed or completed. The client will truncate the blob with [BlobWriter.GetVmo] and get a handle to a vmo in return. The client will then write blob contents into the vmo and call [BlobWriter.BytesReady] on the ’writer` to signal to the server that some number of bytes has been written to the vmo.

pub fn needs_overwrite( &self, blob_hash: &[u8; 32], ) -> QueryResponseFut<BlobCreatorNeedsOverwriteResult, DefaultFuchsiaResourceDialect>

Given the hash of a blob, returns true if it should be overwritten using Create with allow_existing set to true.

impl Proxy for BlobCreatorProxy

type Protocol = BlobCreatorMarker

fn as_channel(&self) -> &AsyncChannel

Get a reference to the proxy’s underlying channel.

fn into_client_end(self) -> Result<ClientEnd<Self::Protocol>, Self>

Attempt to convert the proxy back into a client end.

fn is_closed(&self) -> bool

Returns true if the proxy has received the PEER_CLOSED signal.

fn on_closed(&self) -> OnSignals<'_, Unowned<'_, Handle>>

Returns a future that completes when the proxy receives the PEER_CLOSED signal.
