Safe HaskellNone



Types for referring to remote objects in Remote GHCi. For more details, see Note [External GHCi pointers] in compilerghciGHCi.hs

For details on Remote GHCi, see Note [Remote GHCi] in compilerghciGHCi.hs.



newtype RemotePtr a Source #


RemotePtr Word64 


newtype HValue Source #


HValue Any 

data RemoteRef a Source #

A reference to a remote value. These are allocated and freed explicitly.

mkRemoteRef :: a -> IO (RemoteRef a) Source #

Make a reference to a local value that we can send remotely. This reference will keep the value that it refers to alive until freeRemoteRef is called.

localRef :: RemoteRef a -> IO a Source #

Convert an HValueRef to an HValue. Should only be used if the HValue originated in this process.

freeRemoteRef :: RemoteRef a -> IO () Source #

Release an HValueRef that originated in this process

data ForeignRef a Source #

An HValueRef with a finalizer


NFData (ForeignRef a) # 


rnf :: ForeignRef a -> () Source #

mkForeignRef :: RemoteRef a -> IO () -> IO (ForeignRef a) Source #

Create a ForeignRef from a RemoteRef. The finalizer should arrange to call freeHValueRef on the HValueRef. (since this function needs to be called in the process that created the HValueRef, it cannot be called directly from the finalizer).
