Before the cursor was passed twice as
&mut Cursor
which lead to the second usage failing, since it was already read to the end.Replaced by
&mut v.as_slice()
which is cheaper and does not have to be seek'd back to start.Since transform data is short lived, the input data of
TransformDataFn
must be bound to'r
, which is commonly equiv'w
, but that restriction should be left to the user.
