Data.CompactString.Unsafe
Description
Unsafe functions on CompactStrings.
All these functions can lead to crashes if not used properly.
- unsafeHead :: Encoding a => CompactString a -> Char
- unsafeLast :: Encoding a => CompactString a -> Char
- unsafeTail :: Encoding a => CompactString a -> CompactString a
- unsafeInit :: Encoding a => CompactString a -> CompactString a
- unsafeFromByteString :: ByteString -> CompactString a
Basic interface
unsafeHead :: Encoding a => CompactString a -> CharSource
A variety of head for non-empty CompactString. unsafeHead omits the
check for the empty case, so there is an obligation on the programmer
to provide a proof that the CompactString is non-empty.
unsafeLast :: Encoding a => CompactString a -> CharSource
A variety of last for non-empty CompactString. unsafeLast omits the
check for the empty case, so there is an obligation on the programmer
to provide a proof that the CompactString is non-empty.
unsafeTail :: Encoding a => CompactString a -> CompactString aSource
A variety of tail for non-empty CompactString. unsafeTail omits the
check for the empty case, so there is an obligation on the programmer
to provide a proof that the CompactString is non-empty.
unsafeInit :: Encoding a => CompactString a -> CompactString aSource
A variety of init for non-empty CompactString. unsafeInit omits the
check for the empty case, so there is an obligation on the programmer
to provide a proof that the CompactString is non-empty.
Conversion from ByteString
unsafeFromByteString :: ByteString -> CompactString aSource
Convert a ByteString to a CompactString, does not check whether the ByteString represents a valid string in the encoding a.
