Derive Macro HasId 

#[derive(HasId)]
{
    // Attributes available to this derive:
    #[id_field]
    #[has_id]
}

Implement the configured DBC HasId trait for a named-field structure.

Example

mod support {
    pub trait HasId {
        fn id(&self) -> i32;
    }
}

use support::HasId as _;
use wowlab_engine_macros::HasId;

#[derive(HasId)]
#[id_field = "record_id"]
#[has_id(crate = "crate::support")]
struct Row {
    record_id: i32,
}

fn main() {
    assert_eq!(Row { record_id: 42 }.id(), 42);
}
