Struct TagManager 

pub struct TagManager { /* private fields */ }

Owns the per-(bucket, key) and per-bucket tag state. All operations take the inner RwLock; cloning a manager is intentionally not supported — share via Arc<TagManager>.

Implementations

impl TagManager

pub fn new() -> Self

Empty manager.

pub fn put_object_tags(&self, bucket: &str, key: &str, tags: TagSet)

Replace (or create) the object-level tag set. AWS PutObjectTagging is a full-replace operation (no merge), so we mirror that.

pub fn get_object_tags(&self, bucket: &str, key: &str) -> Option<TagSet>

Borrow-clone the object-level tag set. None when no tags have been set for (bucket, key).

pub fn delete_object_tags(&self, bucket: &str, key: &str)

Drop the object-level tag set for (bucket, key) (idempotent — missing entry is a no-op, matching AWS DeleteObjectTagging).

pub fn put_bucket_tags(&self, bucket: &str, tags: TagSet)

Replace (or create) the bucket-level tag set.

pub fn get_bucket_tags(&self, bucket: &str) -> Option<TagSet>

Borrow-clone the bucket-level tag set.

pub fn delete_bucket_tags(&self, bucket: &str)

Drop the bucket-level tag set (idempotent).

pub fn to_json(&self) -> Result<String, Error>

JSON snapshot for restart-recoverable state. Pair with Self::from_json.

pub fn from_json(s: &str) -> Result<Self, Error>

Restore from a JSON snapshot produced by Self::to_json.
