Overview

A Mutable that stages method calls within a transaction.

Reads use the attempt's current snapshot. Mutations replace only its staged value and are published with the other participants when the attempt commits. Snapshots must be frozen. Use a dedicated transaction participant for a shareable object whose state can change while it remains unfrozen.
