* upb - a minimalist implementation of protocol buffers. |

|
* upb's core components like upb_decoder and upb_msg are carefully designed to |
|
* avoid depending on each other for maximum orthogonality. In other words, |
|
* you can use a upb_decoder to decode into *any* kind of structure; upb_msg is |
|
* just one such structure. A upb_msg can be serialized/deserialized into any |
|
* format, protobuf binary format is just one such format. |
|
* |
|
* However, for convenience we provide functions here for doing common |
|
* operations like deserializing protobuf binary format into a upb_msg. The |
|
* compromise is that this file drags in almost all of upb as a dependency, |
|
* which could be undesirable if you're trying to use a trimmed-down build of |
|
* upb. |
|
* |
|
* While these routines are convenient, they do not reuse any encoding/decoding |
|
* state. For example, if a decoder is JIT-based, it will be re-JITted every |
|
* time these functions are called. For this reason, if you are parsing lots |
|
* of data and efficiency is an issue, these may not be the best functions to |
|
* use (though they are useful for prototyping, before optimizing). |
