Request message for BidiWriteObject.

Fields

write_offset: i64

Required. The offset from the beginning of the object at which the data should be written.

In the first WriteObjectRequest of a WriteObject() action, it indicates the initial offset for the Write() call. The value must be equal to the persisted_size that a call to QueryWriteStatus() would return (0 if this is the first write to the object).

On subsequent calls, this value must be no larger than the sum of the first write_offset and the sizes of all data chunks sent previously on this stream.

An invalid value will cause an error.

object_checksums: Option<ObjectChecksums>

Checksums for the complete object. If the checksums computed by the service don’t match the specified checksums the call will fail. May only be provided in the first or last request (either with first_message, or finish_write set).

state_lookup: bool

For each BidiWriteObjectRequest where state_lookup is true or the client closes the stream, the service will send a BidiWriteObjectResponse containing the current persisted size. The persisted size sent in responses covers all the bytes the server has persisted thus far and can be used to decide what data is safe for the client to drop. Note that the object’s current size reported by the BidiWriteObjectResponse may lag behind the number of bytes written by the client. This field is ignored if finish_write is set to true.

flush: bool

Persists data written on the stream, up to and including the current message, to permanent storage. This option should be used sparingly as it may reduce performance. Ongoing writes will periodically be persisted on the server even when flush is not set. This field is ignored if finish_write is set to true since there’s no need to checkpoint or flush if this message completes the write.

finish_write: bool

If true, this indicates that the write is complete. Sending any WriteObjectRequests subsequent to one in which finish_write is true will cause an error. For a non-resumable write (where the upload_id was not set in the first message), it is an error not to set this field in the final message of the stream.

common_object_request_params: Option<CommonObjectRequestParams>

A set of parameters common to Storage API requests concerning an object.

first_message: Option<FirstMessage>

The first message of each stream should set one of the following.

data: Option<Data>

A portion of the data for the object.

impl PartialEq for BidiWriteObjectRequest

fn eq(&self, other: &BidiWriteObjectRequest) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
