/* A upb::Sink is an object that binds a upb::Handlers object to some runtime
 * state.  It represents an endpoint to which data can be sent.
 *
 * TODO(haberman): right now all of these functions take selectors.  Should they
 * take selectorbase instead?
 *
 * ie. instead of calling:
 *   sink->StartString(FOO_FIELD_START_STRING, ...)
 * a selector base would let you say:
 *   sink->StartString(FOO_FIELD, ...)
 *
 * This would make call sites a little nicer and require emitting fewer selector
 * definitions in .h files.
 *
 * But the current scheme has the benefit that you can retrieve a function
 * pointer for any handler with handlers->GetHandler(selector), without having
 * to have a separate GetHandler() function for each handler type.  The JIT
 * compiler uses this.  To accommodate we'd have to expose a separate
 * GetHandler() for every handler type.
 *
 * Also to ponder: selectors right now are independent of a specific Handlers
 * instance.  In other words, they allocate a number to every possible handler
 * that *could* be registered, without knowing anything about what handlers
 * *are* registered.  That means that using selectors as table offsets prohibits
 * us from compacting the handler table at Freeze() time.  If the table is very
 * sparse, this could be wasteful.
 *
 * Having another selector-like thing that is specific to a Handlers instance
 * would allow this compacting, but then it would be impossible to write code
 * ahead-of-time that can be bound to any Handlers instance at runtime.  For
 * example, a .proto file parser written as straight C will not know what
 * Handlers it will be bound to, so when it calls sink->StartString() what
 * selector will it pass?  It needs a selector like we have today, that is
 * independent of any particular upb::Handlers.
 *
 * Is there a way then to allow Handlers table compaction? */
