The first byte in the sequence contains the lowest 7 bits of the original number. The protobuf program then generates source code from this description for generating or parsing stream of bytes that represent the structured data. Using the example encoding described above, we receive 4 bytes and assuming they represent a 32-bit integer in big-endian order, decode them to get the length. 0: Release: 10. 0 of the Mapbox Vector Tile specification is the clarification of the intent of the intial version of the specification and the definition of interior and exterior rings within polygons.
