-
- The parser object keeps track of a function pointer which represents the
- current parse state.
-
- Each time new bytes are presented, we call into the current state, which
- recursively parses until all bytes in the given chunk are exhausted.
-
- The parse state that terminates then saves its function pointer to be the
- current state so that it can resume when more bytes are available.
-
- It's expected that most optimizing compilers will turn this code into
- a set of indirect jumps, and so not waste stack space. */
