N(base32 X)

Encode argument into EOSIO name. (base32)
Used for fixed name

📘

If you want to convert into EOSIO name from variable, you should use eosio::string_to_name()

Tips

1. To encode a script into EOSIO name, see eosio::string_to_name

2. To decode from base32 and restore to string form, use eosio::to_string() (an alias of std::string)

C++

auto user_name_obj = eosio::name{user}; // account_name user
std::string user_name = user_name_obj.to_string();
