Fixes issue #3462
Motivation
This change implements
OrdandPartialOrdfor the span::Id type in the tracing-core crate. Currently, span::Id only implements Eq, PartialEq, and Hash. Without Ord, subscriber implementations cannot store span IDs in ordered collections like BTreeMap or BTreeSet.Fixes issue #3462.
Solution
Added PartialOrd and Ord traits to the
Idstruct.
