Execute
The execute method doesn’t return anything — a successful execute returns
an Ok(()) — which is convenient for things like updates or commands where
we don’t care about getting output if it works:
Copy
client.execute("update Account set {username := .username ++ '!'};", &())
.await?;
client.execute("create superuser role project;", &())
.await?;
client.execute("alter role project set password := 'GOODpassword';", &())
.await?;
// Returns Ok(()) upon success but error info will be returned
let command = client.execute("create type MyType {};", &()).await;
let command_string = command.unwrap_err().to_string();
assert!(command_string.contains("bare DDL statements are not allowed"));
