Trait HistoryAccess 

pub trait HistoryAccess: Send + Sync {
    // Required methods
    fn all(&self) -> BoxFuture<'_, Result<Vec<Message>>>;
    fn tail(&self, n: usize) -> BoxFuture<'_, Result<Vec<Message>>>;
    fn since(&self, message_id: &str) -> BoxFuture<'_, Result<Vec<Message>>>;
    fn count(&self) -> BoxFuture<'_, Result<usize>>;
}

Async read-only access to a room’s chat history.

Respects DM visibility — a plugin invoked by user X will not see DMs between Y and Z.

Required Methods

fn all(&self) -> BoxFuture<'_, Result<Vec<Message>>>

Load all messages (filtered by DM visibility).

fn tail(&self, n: usize) -> BoxFuture<'_, Result<Vec<Message>>>

Load the last n messages (filtered by DM visibility).

fn since(&self, message_id: &str) -> BoxFuture<'_, Result<Vec<Message>>>

Load messages after the one with the given ID (filtered by DM visibility).

fn count(&self) -> BoxFuture<'_, Result<usize>>

Count total messages in the chat.
