rust derive iterator for newtype

Summary

It is possible to derive an iterator for a newtype in Rust. For example, the macros provided by the newtype_derive crate can be used to derive "obvious" implementations of traits such as Add, Neg, Index, Deref, From, etc.. 1 This allows for compile time guarantees that the right type of value is supplied to a program, such as an age verification function that checks age in years. 2

Summary . That is, given a tuple struct with exactly one field ( e.g. struct Buckets(i32) ), these macros will derive "obvious" implementations of traits such as Add , Neg , Index , Deref , From , etc.

Summary The newtype idiom gives compile time guarantees that the right type of value is supplied to a program. For example, an age verification function that checks age in years, must be given a value of type Years . Uncomment the last print statement to observe that the type supplied must be Years .
