Function cmp 

pub fn cmp(a: &Nibbles, b: &Nibbles) -> Ordering
Available on crate feature trie only.
Expand description

Compares two Nibbles in depth-first order.

In depth-first ordering:

  • Descendants come before their ancestors (children before parents)
  • Siblings are ordered lexicographically

ยงExample

0x11 comes before 0x1 (child before parent)
0x12 comes before 0x1 (child before parent)
0x11 comes before 0x12 (lexicographical among siblings)
0x1 comes before 0x21 (lexicographical among siblings)
Result: 0x11, 0x12, 0x1, 0x21
