+ * The code in the internal::from_chars function is meant to handle the floating-point number parsing
+ * when we have more than 19 digits in the decimal mantissa. This should only be seen
+ * in adversarial scenarios: we do not expect production systems to even produce
+ * such floating-point numbers.
+ *
+ * The parser is based on work by Nigel Tao (at https://github.com/google/wuffs/)
+ * who credits Ken Thompson for the design (via a reference to the Go source
+ * code). See
+ * https://github.com/google/wuffs/blob/aa46859ea40c72516deffa1b146121952d6dfd3b/internal/cgen/base/floatconv-submodule-data.c

+ * It is probably not very fast but it is a fallback that should almost never be
+ * called in real life. Google Wuffs is published under APL 2.0.

+  * last document (the characters after the boundary) has an equal number of
+  * start and end brackets, it is considered complete.

+  * first element of the pair is NOT one of these characters: '{' '[' ':' ','
+  * and when the second element is NOT one of these characters: '}' ']' ':' ','.
+  *
+  * This simple comparison works most of the time, but it does not cover cases
+  * where the batch's structural indexes contain a perfect amount of documents.
+  * In such a case, we do not have access to the structural index which follows
+  * the last document, therefore, we do not have access to the second element in
+  * the pair, and that means we cannot identify the last document. To fix this
+  * issue, we keep a count of the open and closed curly/square braces we found
+  * while searching for the pair. When we find a pair AND the count of open and
+  * closed curly/square braces is the same, we know that we just passed a
+  * complete document, therefore the last json buffer location is the end of the

+//      p2 * 2^e = p2 / 2^-e = d[-1] / 10^1 + d[-2] / 10^2 + ...
