Helo, I'm very newbie in rust.
I'm doing some exercises with rust & mysql but I have a problem.
If I get a row from a table with conn.query_first(.....).map(....) work fine
but If try with the same select instruction with conn.exec_first(....).map
I get error:
thread 'main' panicked at 'Couldn't convert Row.
Dump show that the row is correctly read from mysql.
Can you help me?
