2Iterative JSON parser.

4Main API: 

5 

6- ``ijson.parse``: iterator returning parsing events with the object tree context, 

7 see ``ijson.common.parse`` for docs. 

8 

9- ``ijson.items``: iterator returning Python objects found under a specified prefix, 

10 see ``ijson.common.items`` for docs. 

11 

12Top-level ``ijson`` module exposes method from the pure Python backend. There's 

13also two other backends using the C library yajl in ``ijson.backends`` that have 

14the same API and are faster under CPython.
