Trait UniquenessPolicy 

pub trait UniquenessPolicy {
    type Decorator<T: LinkReference, L: Doublets<T>>: Doublets<T>;

    // Required method
    fn decorate<T, L>(links: L) -> Self::Decorator<T, L>
       where T: LinkReference,
             L: Doublets<T>;
}

Selects how a store reacts when an update would produce a duplicate (source, target) pair.

Implemented by Validate, Resolve and CascadeResolve.

Required Associated Types

type Decorator<T: LinkReference, L: Doublets<T>>: Doublets<T>

The decorator this policy wraps a store in.

Required Methods

fn decorate<T, L>(links: L) -> Self::Decorator<T, L>

where T: LinkReference, L: Doublets<T>,

Wraps links in the decorator selected by this policy.

Dyn Compatibility

This trait is not dyn compatible.

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