Word16 package:bytesmith

Unsigned 16-bit word.

Parse a LEB-128-encoded number. If the number is larger than 0xFFFF, fails with the provided error.

Parse an array of big-endian unsigned 16-bit words. If the host is big-endian, the implementation is optimized to simply memcpy bytes into the result array. The result array always has elements in native-endian byte order.

Array of little-endian unsigned 16-bit words. If the host is little-endian, the implementation is optimized to simply memcpy bytes into the result array. The result array always has elements in native-endian byte order.

Parse a decimal-encoded 16-bit word. If the number is larger than 65535, this parser fails.

Parse exactly four ASCII-encoded characters, interpreting them as the hexadecimal encoding of a 16-bit number. Note that this rejects a sequence such as 5A9, requiring 05A9 instead. This is insensitive to case. This is particularly useful when parsing escape sequences in C or JSON, which allow encoding characters in the Basic Multilingual Plane as \uhhhh.

Parse a hexadecimal-encoded 16-bit word. If the number is larger than 65535, this parser fails. This allows leading zeroes and is insensitive to case. For example, 0100a and 100A would both be accepted as the same number.
