Types

type ByteStreamClient 

type ByteStreamClient interface {
	// `Read()` is used to retrieve the contents of a resource as a sequence
	// of bytes. The bytes are returned in a sequence of responses, and the
	// responses are delivered as the results of a server-side streaming RPC.
	Read(ctx context.Context, in *ReadRequest, opts ...grpc.CallOption) (ByteStream_ReadClient, error)
	// `Write()` is used to send the contents of a resource as a sequence of
	// bytes. The bytes are sent in a sequence of request protos of a client-side
	// streaming RPC.
	//
	// A `Write()` action is resumable. If there is an error or the connection is
	// broken during the `Write()`, the client should check the status of the
	// `Write()` by calling `QueryWriteStatus()` and continue writing from the
	// returned `committed_size`. This may be less than the amount of data the
	// client previously sent.
	//
	// Calling `Write()` on a resource name that was previously written and
	// finalized could cause an error, depending on whether the underlying service
	// allows over-writing of previously written resources.
	//
	// When the client closes the request channel, the service will respond with
	// a `WriteResponse`. The service will not view the resource as `complete`
	// until the client has sent a `WriteRequest` with `finish_write` set to
	// `true`. Sending any requests on a stream after sending a request with
	// `finish_write` set to `true` will cause an error. The client **should**
	// check the `WriteResponse` it receives to determine how much data the
	// service was able to commit and whether the service views the resource as
	// `complete` or not.
	Write(ctx context.Context, opts ...grpc.CallOption) (ByteStream_WriteClient, error)
	// `QueryWriteStatus()` is used to find the `committed_size` for a resource
	// that is being written, which can then be used as the `write_offset` for
	// the next `Write()` call.
	//
	// If the resource does not exist (i.e., the resource has been deleted, or the
	// first `Write()` has not yet reached the service), this method returns the
	// error `NOT_FOUND`.
	//
	// The client **may** call `QueryWriteStatus()` at any time to determine how
	// much data has been processed for this resource. This is useful if the
	// client is buffering data and needs to know which data can be safely
	// evicted. For any sequence of `QueryWriteStatus()` calls for a given
	// resource name, the sequence of returned `committed_size` values will be
	// non-decreasing.
	QueryWriteStatus(ctx context.Context, in *QueryWriteStatusRequest, opts ...grpc.CallOption) (*QueryWriteStatusResponse, error)
