Expand description
These traits are useful for validation during development and testing, to help verify that types
match human expectations. For example, iter-trait uses these traits to ensure that the values
returmed by iter, iter_mut, and into_iter match up in a reasonable manner.
Because these traits provide no actual runtime benefit, if a build uses the release profile,
then these traits will automatically implement for all types to make builds faster and avoid
dead code.
