Struct LegacyOpaqueMetadata 

pub struct LegacyOpaqueMetadata { /* private fields */ }

Ordered opaque legacy metadata.

serde_json::Map uses a key-sorted representation in this workspace. The Legacy result wires promise the received _meta member order remains observable on replay, so this narrow wrapper retains object-member order.

impl LegacyOpaqueMetadata

pub fn get(&self, key: &str) -> Option<&Value>

Returns metadata entries in their original wire order.
