Either\n    `TSInputEncodingUTF8` or `TSInputEncodingUTF16`.\n\n This function returns a syntax tree on success, and `NULL` on failure. There\n are three possible reasons for failure:\n 1.

Or you can start parsing from scratch by first calling\n    `ts_parser_reset`.\n 3. Parsing was cancelled using a cancellation flag that was set by an\n    earlier call to `ts_parser_set_cancellation_flag`.
