Detailed Description
Fixed size byte array sorted lexicographically
Template parameters:
- Size - Size of the fixed_bytes object

function num_words
static static constexpr size_t eosio::fixed_bytes< Size >::num_words()Get number of words contained in this fixed_bytes object.
Get number of words contained in this fixed_bytes object. A word is defined to be 16 bytes in size
function padded_bytes
static static constexpr size_t eosio::fixed_bytes< Size >::padded_bytes()Get number of padded bytes contained in this fixed_bytes object.
Get number of padded bytes contained in this fixed_bytes object. Padded bytes are the remaining bytes inside the fixed_bytes object after all the words are allocated
