Struct MessageMetadata 

pub struct MessageMetadata { /* private fields */ }

Metadata attached to every message in the conversation history.

Skipped during serialization when None to preserve backward compatibility with all existing persistence formats (session archives, snapshots, etc.).

Implementations

pub fn system(timestamp: u64, estimated_tokens: usize) -> Self

Create metadata for a system message.

pub fn synthetic(timestamp: u64, estimated_tokens: usize) -> Self

Create metadata for a synthetic (e.g., recovery/injected) message.
