Trait dock_core::util::batch_update::ValidateUpdate

pub trait ValidateUpdate<Actor, Entity>: GetUpdateKind<Entity> {
    // Required method
    fn ensure_valid(
        &self,
        actor: &Actor,
        entity: &Entity
    ) -> Result<(), UpdateError>;
}

Validates underlying update, so it can be safely applied to the supplied entity.

Required Methods

fn ensure_valid(&self, actor: &Actor, entity: &Entity) -> Result<(), UpdateError>

Ensures that the underlying update is valid.
