#insert error: unable to infer enough type information about `_`

[mfpiccolo]

@sgrif I am setting up a simple server with yaqb and I am running into a problem with insert that I cannot get past. I ultimately keep running into this error when trying to use insert with a NewUser struct.

src/models/user.rs:41:10: 41:49 error: unable to infer enough type information about `_`; type annotations or generic parameter binding required [E0282]
src/models/user.rs:41     conn.insert(&self::users::table, &new_users);

If I switch to insert_returning_count it works fine.

Here is the line causing the error:

It also compiles if I set a return value for the function:

pub fn insert(new_users: Vec<NewUser>) -> Vec<User> {
  User::conn().insert(&self::users::table, &new_users).unwrap().collect()
}

This is a hole in the docs. If you're not going to use the return value, you should use insert_returning_count (which I'm open to other names for as well). insert is only intended to be used when you need the created record (either for ids, timestamps, or the result of some default value)

Leaving this open since there's an actionable problem
