Struct MessageChain 

pub struct MessageChain { /* private fields */ }

Message chain - append-only ordered log of messages. Mirrors Python message chain concept: ordered sequence of messages with digest-based sync support.

Implementations

impl MessageChain

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn messages(&self) -> &[SharedMessage]
