postgresql handler

[fafhrd91]

Handler is impl for DbExecutor so &mut self is DbExecutor instance.

let rows = &self.0.query("SELECT 1;", &[]).unwrap(); // println!("{:?}", rows);

Hooray...
However, the code is a bit magical for a newcomer. why "&self. 0"? Is there a way to have something more accessible like "&self. conn" (in my example)?
Thanks again

change struct definition to this

pub struct DbExecutor{conn: Connection};

[AlbanMinassian]

7 | pub struct DbExecutor(conn: Connection); // &self.conn
  |                           ^ expected one of `!`, `(`, `+`, `,`, `::`, or `<` here

error: expected one of `!`, `(`, `+`, `::`, `;`, `<`, or `where`, found `:`

This is just struct. Use {}

ok
