Crate toql_fields_macro

The fields! macro compiles a list of Toql field names into program code. Any syntax errors or wrong field names will show up at compile time.

Wrong field names are detected because the field! macro uses the query builder functions that are genereated by the Toql derive.

Example

Assume a struct User with a joined address.

use toql_fields_macro::fields;

#[derive(Toql)]
struct User
    #[toql(key)]
    id: u64,
    name: String,
    #[toql(join())]
    address: Address
}

#[derive(Toql)]
struct Address
    #[toql(key)]
    id: u64,
    street: String
}
let f = fields!(User, "*, address_street");

Notice that the fields! macro takes a type, however the resulting Fields is untyped. This is a shortcoming and will be resolved in the future.
