Is not possible use multiple fields using Queryable trait in a struct.

#[derive(Table)]
struct Task {
    id: u64,
    description: String,
    is_done: bool,
}

#[derive(Queryable)]
struct TaskQuery {
    description: String,
    is_done: bool,
}

let mounted_query = Task::table().query(TaskQuery::queryable()).to_sql();

Instead of the wildcard (*) be: SELECT * FROM tasks;, is possible to define the fields in the final query?

Example: SELECT description, is_done FROM tasks;

Excellent approach of this lib, following the concept 'Security by design'.
Thanks.

There's currently a feature gate on line 71 of src/lib.rs. After cloning this repository locally, I can confirm that removing this line has no effect whatsoever, indicating that it was unnecessary to begin with. By removing this, the crate will compile on stable.

The sqlx repo: https://github.com/launchbadge/sqlx
For example, use the following methods

let users:Vec<User> = User::query(&conn)
    .filter(|user| user.id.neq(6).and(user.id.gt(3)))
    .order_by(|user| user.name.then(user.id.ascending()))
    .limit(5)
    .get()
    .await?;

The style code can be the same way of the issue: #2

To insert the increasing IDs can be useful to be able to get the result of the insertion.

This is a very crude example, but I would like to have an interface similar to:

#[derive(Default, Debug, typed_sql::Table)]
struct SomeStruct {
    // It can be represent like NULL if it None.
    // ..or it can just be ignored.
    id: Option<u64>,

    some_useful_data: u128,
}

let insert = SomeStruct::table()
    .insert(SomeStruct::default())
    .returns(|some_struct| some_struct.id)
    .to_sql();

assert_eq!(
    insert,
    "INSERT into somestruct(some_useful_data) VALUES (0) RETURNING id;"
);

Mysql is used more than postgres.

Hey,

I love this project, and I am very excited to try it out, however I ran into a problem, where the name of my table is different from the struct name (as it is namespaced).

Are you able to change the table name in any way for a struct derived with Table?
My code looks like this:

#[derive(Table, FromRow, Debug)]
struct Parent {
    id: i32,
    first_name: String,
    last_name: String,
}

In Diesel I believe they allow you to add #[table_name="people_parent"] to change the name of a table. Do you have a similar feature planned/does it exist?
