/**
 * Represents strategies for halting merged channels when one completes or fails.
 *
 * **Example** (Choosing merge halt strategies)
 *
 * ```ts import.meta.vitest
 * import { Channel } from "effect"
 *
 * // Different halt strategies for channel merging
 * const strategies: Array<Channel.HaltStrategy> = ["left", "right", "both", "either"] // => ["left", "right", "both", "either"]
 * ```
