type Buffer = Ptr Word8

type BufSize = Int

The type for buffer size of each core.

defaultBufSize :: BufSize

The default buffer size (4,096 bytes).

getBuffer :: BufSize -> IO Buffer

freeBuffer :: Buffer -> IO ()

toBufIOWith :: Buffer -> BufSize -> (Buffer -> Int -> IO ()) -> Builder -> IO ()

type FD = FD

closeFD :: FD -> IO ()

openFileFD :: FilePath -> IO FD

getStderrFD :: IO FD

data Builder

Builders denote sequences of bytes. They are Monoids where mempty is the zero-length sequence and mappend is concatenation, which runs in O(1).

Instances

Monoid Builder

Defined in Data.ByteString.Builder.Internal

Methods

mempty :: Builder

mappend :: Builder -> Builder -> Builder

mconcat :: [Builder] -> Builder

Semigroup Builder

Defined in Data.ByteString.Builder.Internal

Methods

(<>) :: Builder -> Builder -> Builder

sconcat :: NonEmpty Builder -> Builder

stimes :: Integral b => b -> Builder -> Builder

ToLogStr Builder

Defined in System.Log.FastLogger.LogStr

Methods

toLogStr :: Builder -> LogStr

data LogStr

Log message builder. Use (<>) to append two LogStr in O(1).
