Struct FencingToken 

pub struct FencingToken {
    pub scope: NamedNode,
    pub epoch: u64,
}

A fencing token: a scope (for example a shard) and a monotonically increasing epoch.

A store that declares fencing rejects an append whose epoch is lower than the highest epoch it has accepted for the scope.

Fields

scope: NamedNode

The scope the epoch counts in, such as a shard IRI.

epoch: u64

The epoch.
