Expand description

A singly-linked list.

Using this data structure only makes sense under very specific circumstances:

  • If you have a list that rarely stores more than one element, then this data-structure can store the element without allocating and only uses as much space as an Option<(T, usize)>. If T can double as the Option discriminant, it will even only be as large as T, usize.

If you expect to store more than 1 element in the common case, steer clear and use a Vec<T>, Box<[T]>, or a SmallVec<T>.
