The inputoutput will be in the form of a list as recognized by toHaskell
fromHaskell
(i.e. the length followed by the elements in sequence).
The function will be mapped over the input list in a lazy manner.
:: (MarshalFeld a, MarshalFeld b) | |

-> ExternalCompilerOpts | |
-> (a -> Run b) | Function to compile |
-> ((HaskellRep a -> IO (HaskellRep b)) -> IO c) | Function that has access to the compiled executable as a function |
-> IO c |
A version of marshalled
that takes ExternalCompilerOpts
as additional
argument
:: (MarshalFeld a, MarshalFeld b) | |
=> (a -> Run b) | Function to compile |
-> ((HaskellRep a -> IO (HaskellRep b)) -> IO c) | Function that has access to the compiled executable as a function |
-> IO c |
Compile a function and make it available as an IO
function. Note that
compilation only happens once, even if the function is used many times in the
body.
For example, given the following Feldspar function:
sumArr :: DIArr Int32 -> Run (Data Int32) sumArr arr = do r <- initRef 0 for (0,1,Excl $ length arr) $ \i -> modifyRef r (+ arrIx arr i) unsafeFreezeRef r
marshalled
can be used as follows:
*Main> marshalled sumArr $ \f -> (f [3,4,5] >>= print) >> (f [6,7,8,9] >>= print)
:: (MarshalFeld a, MarshalFeld b) | |

-> (a -> Run b) | Function to compile |
-> (([HaskellRep a] -> IO [HaskellRep b]) -> IO c) | Function that has access to the compiled executable as a function |
-> IO c |
A version of marshalledStream
that takes ExternalCompilerOpts
as
additional argument
:: (MarshalFeld a, MarshalFeld b) | |
=> (a -> Run b) | Function to compile |
-> (([HaskellRep a] -> IO [HaskellRep b]) -> IO c) | Function that has access to the compiled executable as a function |
-> IO c |
Compile a function and make it available as an IO
function. The compiled
function will be applied repeatedly over the list of inputs producing a list
of outputs. Note that compilation only happens once, even if the function is
used many times in the body.
