Durable connections for use with async
IN THIS PACKAGE

val create : ?time_source:Async_kernel.Time_source.t -> Async_rpc_kernel.Rpc.Connection.t Async_durable__Durable.t -> ( 'query, 'state, 'update, 'error ) Async_rpc_kernel.Rpc.State_rpc.t -> query:'query -> resubscribe_delay:Core.Time.Span.t -> ( 'state, 'update, 'error, Async_rpc_kernel.Rpc.State_rpc.Metadata.t ) Update.t Async_kernel.Pipe.Reader.t

create will immediately dispatch the the supplied Rpc.State_rpc.t with query over the Rpc.Connection.t Async_durable.t. If a connection attempt fails or if the subscription closes, it waits resubscribe_delay and dispatches again to create a new subscription. The pipe returned by create contains all the responses that come over the internal subscription, as well as updates about the state of the t.

Closing the returned pipe will permanently close the subscription.

It is guaranteed that every Connection_success message will be immediately followed by a State message.

val create_or_fail : ?time_source:Async_kernel.Time_source.t -> Async_rpc_kernel.Rpc.Connection.t Async_durable__Durable.t -> ( 'query, 'state, 'update, 'error ) Async_rpc_kernel.Rpc.State_rpc.t -> query:'query -> resubscribe_delay:Core.Time.Span.t -> ( ( 'state, 'update, 'error, Async_rpc_kernel.Rpc.State_rpc.Metadata.t ) Update.t Async_kernel.Pipe.Reader.t, 'error ) Core.Result.t Core.Or_error.t Async_kernel.Deferred.t

create_or_fail will return an Error e if the initial attempt to dispatch the supplied Rpc.Pipe_rpc.t does not succeed, or an Ok (Error 'error) if the initial dispatch returns a server side rpc error.

create_versioned, create_or_fail_versioned, create_versioned', create_or_fail_versioned' are identical to create and create_or_fail but work for Caller_converts and Both_converts Versioned State RPCs.

module Expert : sig ... end

Expert is only used to build Durable_pipe_rpc off the same implementation as Durable_state_rpc. If other similar Rpcs come into being, they can also take advantage.
