Trait AssociatedObject 

Source 
pub trait AssociatedObject: Send + Sync {
    // Provided method
    fn will_apply_mutation(
        &self,
        _mutation: &Mutation,
        _object_id: u64,
        _manager: &ObjectManager,
    ) { ... }
}
Expand description

Mutations in a transaction can be associated with an object so that when mutations are applied, updates can be applied to in-memory structures. For example, we cache object sizes, so when a size change is applied, we can update the cached object size.

Provided Methods§

Source

fn will_apply_mutation( &self, _mutation: &Mutation, _object_id: u64, _manager: &ObjectManager, )

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
