Expand description
A trait for defining a pair of items of the same type.
This trait is meant to generalize having two similar things.
It is implemented for (T, T)
and [T; 2]
with Item = T
.
However, because a pair does not necessarily have to be an
Actual pair It is also implemented for (T, T, T, T)
and
[T; 4]
with Item = (T, T)
and Item = [T; 2]
respectively.
