_nul :: Word16 Source

isSpace :: Word16 -> Bool Source

word16ToChar :: Word16 -> Char Source

Total conversion to char.

create :: Int -> (forall s. MBA s -> ST s ()) -> ShortByteString Source

asBA :: ShortByteString -> BA Source

data BA Source

data MBA s Source

newPinnedByteArray :: Int -> ST s (MBA s) Source

newByteArray :: Int -> ST s (MBA s) Source

copyByteArray :: BA -> Int -> MBA s -> Int -> Int -> ST s () Source

unsafeFreezeByteArray :: MBA s -> ST s BA Source

copyAddrToByteArray :: Ptr a -> MBA RealWorld -> Int -> Int -> ST RealWorld () Source

packCWString :: Ptr Word16 -> IO ShortByteString Source

O(n). Construct a new ShortByteString from a CWString. The resulting ShortByteString is an immutable copy of the original CWString, and is managed on the Haskell heap. The original CWString must be null terminated.

Since: os-string-0.10.10.0

packCWStringLen :: (Ptr Word16, Int) -> IO ShortByteString Source

O(n). Construct a new ShortByteString from a CWStringLen. The resulting ShortByteString is an immutable copy of the original CWStringLen. The ShortByteString is a normal Haskell value and will be managed on the Haskell heap.

Since: os-string-0.10.10.0

useAsCWString :: ShortByteString -> (Ptr Word16 -> IO a) -> IO a Source

O(n) construction. Use a ShortByteString with a function requiring a null-terminated CWString. The CWString is a copy and will be freed automatically; it must not be stored or used after the subcomputation finishes.

Since: os-string-0.10.10.0

useAsCWStringLen :: ShortByteString -> ((Ptr Word16, Int) -> IO a) -> IO a Source

O(n) construction. Use a ShortByteString with a function requiring a CWStringLen. As for useAsCWString this function makes a copy of the original ShortByteString. It must not be stored or used after the subcomputation finishes.

Since: os-string-0.10.10.0

newCWString :: ShortByteString -> IO (Ptr Word16) Source

O(n) construction. Use a ShortByteString with a function requiring a CWStringLen. As for useAsCWString this function makes a copy of the original ShortByteString. It must not be stored or used after the subcomputation finishes.

Since: os-string-0.10.10.0

moduleErrorIO :: String -> String -> IO a Source

moduleErrorMsg :: String -> String -> String Source

packWord16 :: [Word16] -> ShortByteString Source

packLenWord16 :: Int -> [Word16] -> ShortByteString Source

unpackWord16 :: ShortByteString -> [Word16] Source

packWord16Rev :: [Word16] -> ShortByteString Source

packLenWord16Rev :: Int -> [Word16] -> ShortByteString Source

writeWord16Array Source

Encode Word16 as little-endian.

indexWord8Array Source

indexWord16Array Source

Decode Word16 from little-endian.

word16ToLE# :: Word16# -> Word16# Source

word16FromLE# :: Word16# -> Word16# Source

setByteArray :: MBA s -> Int -> Int -> Int -> ST s () Source

copyMutableByteArray :: MBA s -> Int -> MBA s -> Int -> Int -> ST s () Source

createAndTrim :: Int -> (forall s. MBA s -> ST s (Int, a)) -> (ShortByteString, a) Source

Given the maximum size needed and a function to make the contents of a ShortByteString, createAndTrim makes the ShortByteString. The generating function is required to return the actual final size (<= the maximum size) and the result value. The resulting byte array is realloced to this size.

createAndTrim' :: Int -> (forall s. MBA s -> ST s Int) -> ShortByteString Source

createAndTrim'' :: Int -> (forall s. MBA s -> MBA s -> ST s (Int, Int)) -> (ShortByteString, ShortByteString) Source

findIndexOrLength :: (Word16 -> Bool) -> ShortByteString -> Int Source

findFromEndUntil :: (Word16 -> Bool) -> ShortByteString -> Int Source

Returns the length of the substring matching, not the index. If no match, returns 0.

assertEven :: ShortByteString -> ShortByteString Source

errorEmptySBS :: HasCallStack => String -> a Source

moduleError :: HasCallStack => String -> String -> a Source
