Hey all,
Thanks for the library! I'd like to contribute something that I've wanted a few times when working with py-tree-sitter.
As a note, I'm not very well-versed in C or writing Python extensions, so although this seems pretty simple, a critical eye would be appreciated.
This PR adds a
__hash__
method to the Node class. This makes it possible to add Node instances to sets or use them as dictionary keys. I've tested and found the hash to work well and be consistently the same for a given node, and consistently different for different nodes as you'd expect.
