Enum RequestTarget

#[non_exhaustive]
pub enum RequestTarget<'a> {
    Any,
    InstanceName(&'a str),
    BucketId(u64, bool),
    TierAndBucketId(&'a str, u64, bool),
    ReplicasetName(&'a str, bool),
}

An enumeration of possible target specifiers for RPC requests. Determines which instance in the picodata cluster the request should be sent to.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Any

Any instance running the corresponding service.

InstanceName(&'a str)

The specific instance with a given instance name.

BucketId(u64, bool)

An instance in the replicaset in tier of target instance which currently stores the bucket with the specified id.

If the boolean parameter is true, then send the request to the replicaset master, otherwise any replica.

TierAndBucketId(&'a str, u64, bool)

An instance in the replicaset in the tier which currently stores the bucket with the specified id.

If the boolean parameter is true, then send the request to the replicaset master, otherwise any replica.

ReplicasetName(&'a str, bool)

An instance in the replicaset determined by the explicit replicaset name.

If the boolean parameter is true, then send the request to the replicaset master, otherwise any replica.
