Metadata associated with an Object.

Fields

id: Option<String>

The ID of the object, including the bucket name, object name, and generation number.

self_link: Option<String>

The link to this object.

name: Option<String>

The name of the object. Required if not specified by URL parameter. writable

bucket: Option<String>

The name of the bucket containing this object.

generation: Option<i64>

The content generation of this object. Used for object versioning.

metageneration: Option<i64>

The version of the metadata for this object at this generation. Used for preconditions and for detecting changes in metadata. A metageneration number is only meaningful in the context of a particular generation of a particular object.

content_type: Option<String>

Content-Type of the object data. If an object is stored without a Content-Type, it is served as application/octet-stream. writable

content_disposition: Option<String>

Content-Disposition of the object data. writable

content_encoding: Option<String>

Content-Encoding of the object data. writable

time_created: Option<Timestamp>

The creation time of the object in RFC 3339 format.

updated: Option<Timestamp>

The modification time of the object metadata in RFC 3339 format.

storage_class: Option<StorageClass>

Storage class of the object. writable

time_storage_class_updated: Option<Timestamp>

The time at which the object’s storage class was last changed. When the object is initially created, it will be set to timeCreated.

size: Option<u64>

Content-Length of the data in bytes.

md5_hash: Option<String>

MD5 hash of the data; encoded using base64. For more information about using the MD5 hash, see Hashes and ETags: Best Practices. writable

media_link: Option<String>

Media download link.

content_language: Option<String>

Content-Language of the object data. writable

crc32c: Option<String>

CRC32c checksum, as described in RFC 4960, Appendix B; encoded using base64 in big-endian byte order. For more information about using the CRC32c checksum, see Hashes and ETags: Best Practices.

etag: Option<String>

HTTP 1.1 Entity tag for the object.

metadata: Option<BTreeMap<String, String>>

User-provided metadata, in key/value pairs. writable
