Struct DamlActiveContractsService 

pub struct DamlActiveContractsService<'a> { /* private fields */ }

Returns a stream of the active contracts on a Daml ledger.

Allows clients to initialize themselves according to a fairly recent state of the ledger without reading through all transactions that were committed since the ledger’s creation.

Getting an empty stream means that the active contracts set is empty and the client should listen to transactions using DamlLedgerOffsetBoundary::Begin. Clients SHOULD NOT assume that the set of active contracts they receive reflects the state at the ledger end.
