This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

len

Public Function
std.DoublyLinkedList.len
pub fn len(list: DoublyLinkedList) usize

Iterate over all nodes, returning the count.

This operation is O(N). Consider tracking the length separately rather than computing it.
