The implementation looks reasonable to me, but this will need T-libs-api approval. r? libs-api |

Implement `Random` for tuples of arity 12 or less. Each element is expected to implement `Random`.

Seems reasonable given the current unstable trait. Whether we end up with this exact trait is another question, but this seems reasonable for unstable. @bors r+ rollup |

Rollup merge of #136801 - sorairolake:add-random-for-tuple, r=joshtriplett Implement `Random` for tuple Implement `Random` for tuples of arity 12 or less. Each element is expected to implement `Random`. I think it's OK to implement this trait for the following types: - Primitive integer types and `bool` - Arrays and tuples of the above values - ~~`NonZero<T>`~~, `Saturating<T>` and `Wrapping<T>` The necessity of this trait is debated (<#130703 (comment)>), but if we decide to keep it in the future when the `random` module is stabilized, I think it would be useful to have this trait implemented for tuples. Tracking issue: #130703 r? `@joboet`
