serde + Ord impls on ArrayStr#77
Merged
Merged
Conversation
Lets ArrayStr<N> participate in serde-driven payloads (versioned telemetry) and be used as a BTreeMap key (lex-ordered on UTF-8 content).
Adds Ord/PartialOrd to ArrayVec (lex-cmp on as_slice) so ArrayStr can delegate. Adds TryFrom<ArrayVec<u8, N>> for ArrayStr<N> (validates UTF-8) so deserialize is just deser-into-ArrayVec then try_from.
