Trait FilterableEntity

pub trait FilterableEntity {
    // Required method
    fn filterable_fields() -> HashSet<String>;

    // Provided method
    fn sortable_fields() -> HashSet<String> { ... }
}

Expand description

Trait for entities to declare which fields are allowed in filter queries.

Implementing this trait on an entity enables field-level access control for the filter DSL, preventing clients from filtering on internal or sensitive columns (e.g., password_hash, internal_notes).

§Example

use backbone_orm::FilterableEntity;
use std::collections::HashSet;

struct User;

impl FilterableEntity for User {
    fn filterable_fields() -> HashSet<String> {
        ["id", "username", "email", "status", "created_at"]
            .iter().map(|s| s.to_string()).collect()
    }
}
