Detailed Description

template<typename K, typename KSerialiser, typename Unit = ccf::kv::serialisers::ZeroBlitUnitCreator>
class ccf::kv::TypedSet< K, KSerialiser, Unit >

Defines the schema of a set type accessed by a ccf::Tx. This set is an unordered container of unique keys. Each key is either present or missing within the set, and key presence can be efficiently tested.

K defines the type of each entry in this set. KSerialiser determines how each K is serialised and deserialised, so they may be written to the ledger and replicated by the consensus algorithm. Note that equality is always evaluated on the serialised form; if unequal Ks produce the same serialisation, they will coincide within this set.

This is implemented as a ccf::kv::Map from K to Unit, and the serialisation of the unit values is overridable with the Unit template parameter.
