Out of curiosity, what is this timestamp field used for? If you retrieve an ast node from the parsed ast tree, then make some edit to the buffer and thus change the ast tree, the node you retrieved will be outdated. Each parser and node has a timestamp, parser’s timestamp increments when an edit is made. Treesit checks if the node’s timestamp equals to that of its associated parser whenever we use a node. Though because parsers are lazy, even if the buffer content has changed, a node won’t be marked outdated until the parser parses the change.
