impl FromSql<Date, Sqlite> for *const str

[+]

The returned pointer is only valid for the lifetime to the argument of from_sql. This impl is intended for uses where you want to write a new impl in terms of String, but don't want to allocate. We have to return a raw pointer instead of a reference with a lifetime due to the structure of FromSql
