Trait Variant

pub trait Variant: Sized {
    type Item;
    type Prev: Refs;
    type Next: Refs;
    type Ends: Refs;
}

Variant defining SelfRefCol specifications.

Required Associated Types

type Item

Elements of the collection.

type Prev: Refs

The way the previous node references will be stored.

• RefsNone if there is no reference.
• RefsSingle if there is zero or one reference.
• RefsArray if there is a constant number of references.
• RefsVec if there is a dynamic number of references.

type Next: Refs

The way the next node references will be stored.

• RefsNone if there is no reference.
• RefsSingle if there is zero or one reference.
• RefsArray if there is a constant number of references.
• RefsVec if there is a dynamic number of references.

type Ends: Refs

The way the ends of the collection will be stored, such as the front of a linked list or root of a tree.

• RefsNone if there is no reference.
• RefsSingle if there is zero or one reference.
• RefsArray if there is a constant number of references.
• RefsVec if there is a dynamic number of references.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
