Capnp.Rpc.Untyped
Contents
Description
This module does not deal with schema-level concepts; all capabilities, methods etc. as used here are untyped.
Synopsis
- data ConnConfig = ConnConfig {
- maxQuestions :: !Word32
- maxExports :: !Word32
- debugMode :: !Bool
- getBootstrap :: Supervisor -> STM (Maybe Client)
- withBootstrap :: Maybe (Supervisor -> Client -> IO ())
- handleConn :: Transport -> ConnConfig -> IO ()
- data Client
- call :: CallInfo -> Client -> STM ()
- nullClient :: Client
- class IsClient a where
- toClient :: a -> Client
- fromClient :: Client -> a
- export :: Supervisor -> ServerOps IO -> STM Client
- clientMethodHandler :: Word64 -> Word16 -> Client -> MethodHandler IO p r
- data RpcError
- data Exception = Exception {}
- data Exception'Type
Connections to other vats
data ConnConfig Source #
Configuration information for a connection.
Constructors

Fields

Instances
| Default ConnConfig Source # | |
Defined in Capnp.Rpc.Untyped Methods def :: ConnConfig # | |
handleConn :: Transport -> ConnConfig -> IO () Source #
Handle a connection to another vat. Returns when the connection is closed.
Clients for capabilities
A reference to a capability, which may be live either in the current vat or elsewhere. Holding a client affords making method calls on a capability or modifying the local vat's reference count to it.
nullClient :: Client Source #
A null client. This is the only client value that can be represented statically. Throws exceptions in response to all method calls.
class IsClient a where Source #
Types which may be converted to and from Clients. Typically these
will be simple type wrappers for capabilities.
Methods
toClient :: a -> Client Source #
Convert a value to a client.
fromClient :: Client -> a Source #
Convert a client to a value.

Exporting local objects
export :: Supervisor -> ServerOps IO -> STM Client Source #
Spawn a local server with its lifetime bound to the supervisor, and return a client for it. When the client is garbage collected, the server will be stopped (if it is still running).
clientMethodHandler :: Word64 -> Word16 -> Client -> MethodHandler IO p r Source #
Errors
Errors which can be thrown by the rpc system.
Constructors
| ReceivedAbort Exception | The remote vat sent us an abort message. |
| SentAbort Exception | We sent an abort to the remote vat. |
