The type var hexadecimal values.

of_char c is the the hexadecimal encoding of the character c.

to_char x y is the character correspondong to the xy hexadecimal encoding.

of_string s is the hexadecimal representation of the binary string s. If ignore is set, skip the characters in the list when converting. Eg of_string ~ignore:[' '] "a f". The default value of ignore is []).

to_string t is the binary string s such that of_string s is t.

of_cstruct buf is the hexadecimal representation of the buffer buf.

to_cstruct t is the buffer b such that of_cstruct b is t.

hexdump h dumps the hex encoding to stdout in the following format:

   00000000: 6865 6c6c 6f20 776f 726c 6420 6865 6c6c  hello world hell
   00000010: 6f20 776f 726c 640a                      o world.

This is the same format as emacs hexl-mode, and is a very similar format to hexdump -C. '\t' and '\n' are printed as '.'.in the char column.

print_row_numbers and print_chars both default to true. Setting either to false does not print the column.

Same as hexdump except returns a string.
