/* A generic stream is inspired from the libc streams, which mainly serve
 * for interacting with local files. Using such a stream, you can read,
 * write and seek (move the cursor to a specific offset in the stream).
 *
 * Offset types, for seeking, are the following:
 *
 * `SET`: set the current position to the offset.
 * `CUR`: add the offset to the current position.
 * `END`: set the current position to the end minus the offset.
 * `DATA`: seek to the next data.
 * `HOLE`: seek to the next hole. */
