Define a typed exception struct implementing RokException.

Self-handled exceptions (default) also implement axum::IntoResponse when the axum feature is enabled.

Example

use rok_core::rok_exception;

rok_exception! {
    /// Raised when a query returns no rows.
    pub struct E_ROW_NOT_FOUND {
        status = 404,
        self_handled = false,
        fields: {
            pub model: Option<&'static str>,
            pub id: Option<String>,
        },
    }
}
