Enum MessageKind 

pub enum MessageKind {
    Live,
    History {
        server_message_id: u64,
    },
    Divider,
    LoadMore(LoadMoreDirection),
    System,
}

What a row is.

Note LoadMore and Divider: under xtext both were ordinary text rows whose meaning was recovered by string-matching the rendered bytes — chat_history_word_click compared the clicked word against a composed “↑\u{a0}Load\u{a0}older\u{a0}messages” sentinel, non-breaking spaces and all, because xtext’s tokenizer splits on ASCII space. Making them row kinds retires that.

Variants

Live

A live message from the server.

History

A backfilled message, carrying the server’s message id so the paging cursor can be derived from the buffer rather than tracked alongside it.

Fields

server_message_id: u64

Divider

A rule with a caption (“chat history (12 messages)”).

LoadMore(LoadMoreDirection)

The clickable paging row.

System

Client-generated notice — connection state, task errors, /me output, the old INFOPREFIX lines.

Implementations

impl MessageKind

pub fn is_history(&self) -> bool

Part of a chat-history block: backfilled messages and the rows that frame them. These don’t count against the scrollback cap — the user asked for them — and are never trimmed to make room for live rows.
