Request message for ReadObject.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

bucket: String

Required. The name of the bucket containing the object to read.

object: String

Required. The name of the object to read.

generation: i64

Optional. If present, selects a specific revision of this object (as opposed to the latest version, the default).

read_offset: i64

Optional. The offset for the first byte to return in the read, relative to the start of the object.

A negative read_offset value will be interpreted as the number of bytes back from the end of the object to be returned. For example, if an object’s length is 15 bytes, a ReadObjectRequest with read_offset = -5 and read_limit = 3 would return bytes 10 through 12 of the object. Requesting a negative offset with magnitude larger than the size of the object will return the entire object.

read_limit: i64

Optional. The maximum number of data bytes the server is allowed to return in the sum of all Object messages. A read_limit of zero indicates that there is no limit, and a negative read_limit will cause an error.

If the stream returns fewer bytes than allowed by the read_limit and no error occurred, the stream includes all data from the read_offset to the end of the resource.

if_generation_match: Option<i64>

Makes the operation conditional on whether the object’s current generation matches the given value. Setting to 0 makes the operation succeed only if there are no live versions of the object.

if_generation_not_match: Option<i64>

Makes the operation conditional on whether the object’s live generation does not match the given value. If no live object exists, the precondition fails. Setting to 0 makes the operation succeed only if there is a live version of the object.

if_metageneration_match: Option<i64>

Makes the operation conditional on whether the object’s current metageneration matches the given value.

if_metageneration_not_match: Option<i64>

Makes the operation conditional on whether the object’s current metageneration does not match the given value.

common_object_request_params: Option<CommonObjectRequestParams>

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

read_mask: Option<FieldMask>

Mask specifying which fields to read. The checksummed_data field and its children will always be present. If no mask is specified, will default to all fields except metadata.owner and metadata.acl.

• may be used to mean “all fields”.

Trait Implementations

impl Clone for ReadObjectRequest

fn clone(&self) -> ReadObjectRequest

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ReadObjectRequest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Message for ReadObjectRequest

fn typename() -> &'static str
