Struct ObjectStoreMetricSample

    pub operation: ObjectStoreOperation,
    pub elapsed_micros: u128,
    pub attempts: u32,
    pub result: ObjectStoreResultClass,
    pub bytes_in: Option<u64>,

}

One object-store call sample delivered to an object-store metrics recorder.

Samples intentionally classify keys and errors instead of exposing raw object keys or provider error strings.

Fields

operation: ObjectStoreOperation

Contract operation that produced the sample.

elapsed_micros: u128

End-to-end operation latency in microseconds, including provider waits.

attempts: u32

Provider attempts this one call made, counting the first: 1 is a call that never retried.

Retries are what makes an otherwise unexplained elapsed_micros readable. The count covers the bounded retry loops inside the store this wrapper measures; a retry loop that sits above the wrapper — crate::ObjectStore::put_immutable_verified is the one — surfaces as one sample per attempt instead, because each of its attempts really is a separate measured call.

result: ObjectStoreResultClass

Cardinality-bounded success or failure classification.

bytes_in: Option<u64>

Request payload bytes for a put, including failed attempts; otherwise None.

bytes_out: Option<u64>

Response payload bytes for a successful get, including zero; otherwise None.

item_count: Option<u64>

Keys yielded by a listing before completion or drop; otherwise None.

key_class: KeyClass

Durable-family grouping derived without retaining the raw key.

range_class: Option<RangeClass>

Read-range or listing shape when applicable; otherwise None.

put_mode: Option<PutModeClass>

Requested conditional-write class for a put; otherwise None.

store_kind: Option<String>

Deployment-supplied provider label, or None when the wrapper was left unlabeled.
