This library allows conversion between the types from @Data.ByteString@ (package @bytestring@) and @Data.Vector.Storable@ (package @vector@) without copying the underlying data. This is useful, for example, when @ByteString@ IO produces or consumes vectors of numbers in native byte order. . The conversion relies on the fact that @ByteString@ and @Vector@ use their respective @ForeignPtr@s in compatible ways. . This library is a fork of the @spool@ package written by Keegan McAllister.
