sse_kms_key_id: Option<String>

KMS key ID used for server-side encryption.

sse_bucket_key_enabled: Option<bool>

Whether an S3 Bucket Key is enabled for SSE-KMS.

sse_customer_algorithm: Option<String>

Customer-provided encryption algorithm for SSE-C.

sse_customer_key_md5: Option<String>

Base64-encoded MD5 of the customer-provided encryption key.

tagging: Vec<(String, String)>

Object tags as key-value pairs.

acl: CannedAcl

Canned ACL applied to this object.

object_lock_mode: Option<String>
