Enum Renderer

pub enum Renderer<A, B> {
    Primary(A),
    Secondary(B),
}

A renderer A with a fallback strategy B.

This type can be used to easily compose existing renderers and create custom, type-safe fallback strategies.

Variants

Primary(A)

The primary rendering option.

Secondary(B)

The secondary (or fallback) rendering option.
