Implement Random for tuple by sorairolake · Pull Request #136801 · rust-lang/rust (original) (raw)

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
