pub fn read_value(buf: &[u8], offset: usize) -> Option<Value>Expand description
Read a scalar msgpack value at offset into nodedb_types::Value.
Handles null, bool, integers, floats, strings, and instant ext
(fixext8 type 1 / 2 → Value::DateTime / Value::NaiveDateTime).
For complex types (array, map, bin, other ext), returns None — caller
should use json_from_msgpack for those.
