class Buffer b where

Immutable memory buffer

Methods

buffer :: b -> (ByteArray# -> a) -> (Addr# -> a) -> a

Instances

Buffer ByteArray

Defined in Data.MemPack.Buffer

Methods

bufferByteCount :: ByteArray -> Int

buffer :: ByteArray -> (ByteArray# -> a) -> (Addr# -> a) -> a

Buffer ByteString

Defined in Data.MemPack.Buffer

Methods

bufferByteCount :: ByteString -> Int

buffer :: ByteString -> (ByteArray# -> a) -> (Addr# -> a) -> a

Buffer ShortByteString

Defined in Data.MemPack.Buffer

Methods

bufferByteCount :: ShortByteString -> Int

buffer :: ShortByteString -> (ByteArray# -> a) -> (Addr# -> a) -> a

newMutableByteArray :: Bool -> Int -> ST s (MutableByteArray s)

freezeMutableByteArray :: MutableByteArray d -> ST d ByteArray

withPtrByteStringST :: ByteString -> (Ptr a -> ST s b) -> ST s b

It is ok to use ByteString withing ST, as long as underlying pointer is never mutated or returned from the supplied action.

pinnedByteArrayToByteString :: ByteArray -> ByteString

pinnedByteArrayToForeignPtr :: ByteArray# -> ForeignPtr a

byteArrayToShortByteString :: ByteArray -> ShortByteString

byteArrayFromShortByteString :: ShortByteString -> ByteArray
