Return a mask of all string characters plus end quotes. prev_escaped is overflow saying whether the next character is escaped. prev_in_string is over

return non-zero if not a structural or whitespace char zero otherwise

Again in str4ncmp we use a memcpy to avoid undefined behavior. The memcpy may appear expensive. Yet all decent optimizing compilers will compile memcp

Check whether the current bytes are valid UTF-8.

We call a fallback floating-point parser that might be slow. Note it will accept JSON numbers, but the JSON spec. is more restrictive so before you ca

We sometimes call trailing_zero on inputs that are zero, but the algorithms do not end up using the returned value. Sadly, sanitizers are not smart en

returns a value with the high 16 bits set if not valid otherwise returns the conversion of the 4 hex digits at src into the bottom 16 bits of the 32-b

Helper to turn unprintable or newline characters into spaces

Convert a mantissa, an exponent and a sign bit into an ieee64 double. The real_exponent needs to be in [0, 2046] (technically real_exponent = 2047 wou

The only problem that can happen at EOF is that a multibyte character is too short or a byte value too large in the last bytes: check_special_cases on

do not forget to call check_eof!

This should always succeed since it follows a call to parse_number.

Inspired by https://lemire.me/blog/2019/04/17/parsing-short-hexadecimal-strings-efficiently/ Ruby addresses in heap dump are hexadecimal strings "0x00

Leaving these here so they can be inlined if so desired

The allocate_padded_buffer function is a low-level function to allocate memory with padding so we can read past the "length" bytes safely. It is used
