   2.237- * The [`TSInput`] parameter lets you specify how to read the text. It has the
   2.238- * following three fields:
   2.239- * 1. [`read`]: A function to retrieve a chunk of text at a given byte offset
   2.240- *    and (row, column) position. The function should return a pointer to the
   2.241- *    text and write its length to the [`bytes_read`] pointer. The parser does
   2.242- *    not take ownership of this buffer; it just borrows it until it has
   2.243- *    finished reading it. The function should write a zero value to the
   2.244- *    [`bytes_read`] pointer to indicate the end of the document.
   2.245- * 2. [`payload`]: An arbitrary pointer that will be passed to each invocation
   2.246- *    of the [`read`] function.
   2.247- * 3. [`encoding`]: An indication of how the text is encoded. Either
   2.248- *    `TSInputEncodingUTF8` or `TSInputEncodingUTF16`.

   2.250- * This function returns a syntax tree on success, and `NULL` on failure. There
   2.251- * are three possible reasons for failure:
   2.252- * 1. The parser does not have a language assigned. Check for this using the
   2.253-      [`ts_parser_language`] function.
   2.254- * 2. Parsing was cancelled due to a timeout that was set by an earlier call to
   2.255- *    the [`ts_parser_set_timeout_micros`] function. You can resume parsing from
   2.256- *    where the parser left out by calling [`ts_parser_parse`] again with the
   2.257- *    same arguments. Or you can start parsing from scratch by first calling
   2.258- *    [`ts_parser_reset`].
   2.259- * 3. Parsing was cancelled using a cancellation flag that was set by an
   2.260- *    earlier call to [`ts_parser_set_cancellation_flag`]. You can resume parsing
   2.261- *    from where the parser left out by calling [`ts_parser_parse`] again with

  2.1253- * Set the allocation functions used by the library.
  2.1254- *
  2.1255- * By default, Tree-sitter uses the standard libc allocation functions,
  2.1256- * but aborts the process when an allocation fails. This function lets
  2.1257- * you supply alternative allocation functions at runtime.
  2.1258- *
  2.1259- * If you pass `NULL` for any parameter, Tree-sitter will switch back to
  2.1260- * its default implementation of that function.
  2.1261- *
  2.1262- * If you call this function after the library has already been used, then
  2.1263- * you must ensure that either:
  2.1264- *  1. All the existing objects have been freed.
  2.1265- *  2. The new allocator shares its state with the old one, so it is capable
  2.1266- *     of freeing memory that was allocated by the old allocator.
