Module show_notes::e031::unions

Demonstrate unions! Combines an enum and a union into a struct that acts mostly like a regular Rust enum.

Structs

• Either
  Uses an enum and a union to get close to a regular Rust enum.
• Wrapped
  A simple type designed to demo unions. See the body of demo_union.

Enums

• Tag
  For tagging the type in Either. See the body of demo_union.

Functions

• demo_union
  Builds an instance of Either, a manually-managed “tagged union” type.

Unions

• EitherValue
  A union, to be used as the inner value for Either.
