Field k a bb within
an a, where a must be a struct type.
What sort of field is this? This corresponds to the slot/group variants
in the Field type in schema.capnp. Mostly used at the type level with

numCaps gets the number of capabilities in a message's capability
table.

Building messages in pure code

Instances
createPure :: (MonadThrow m, Thaw a) => WordCount -> (forall s. PureBuilder s (Mutable s a)) -> m a Source #
createPure limit mm, then freezes it without copying. If m calls throwM then
createPure rethrows the exception in the specified monad.
Canonicalizing messages
canonicalize :: (RWCtx m s, MonadReadMessage mutIn m) => Struct mutIn -> m (Message ('Mut s), Segment ('Mut s)) Source #
Return a canonicalized message with a copy of the given struct as its root. returns a (message, segment) pair, where the segment is the first and only segment of the returned message.
In addition to the usual reasons for failure when reading a message (traversal limit, malformed messages), this can fail if the message does not fit in a single segment, as the canonical form requires single-segment messages.
Implementing RPC servers
type MethodHandler p r = Raw 'Const p -> Fulfiller (Raw 'Const r) -> IO () Source #
Type alias for a handler for a particular rpc method.
class SomeServer a where Source #
Base class for things that can act as capnproto servers.

Methods
shutdown :: a -> IO () Source #
Called when the last live reference to a server is dropped.
unwrap :: Typeable b => a -> Maybe b Source #
Try to extract a value of a given type. The default implementation
always fails (returns Nothing). If an instance chooses to implement
this, it will be possible to use "reflection" on clients that point
at local servers to dynamically unwrap the server value. A typical
implementation will just call Typeable's cast method, but this
needn't be the case -- a server may wish to allow local peers to
unwrap some value that is not exactly the data the server has access
to.
class (IsCap i, HasTypeId i) => Export i Source #
Generated interface types have instances of Export, which allows a server
for that interface to be exported as a Client.
Minimal complete definition
Associated Types
type Server i :: * -> Constraint Source #

if Server i ss is a server for interface i.
The code generator generates a type class for each interface, and
this will aways be an alias for that type class.
