Text Messages

Plain text replies cover four destinations in BotRS, each backed by its own *Params struct and send API call. The destination examples:

• Channel @-mentions: examples/guild/reply_text.rs
• Channel reply with quoted reference: examples/guild/reply_reference.rs
• Group messages (QQ groups): examples/group/reply_text.rs
• C2C (single-user) messages: examples/c2c/reply_text.rs
• Direct messages inside guilds: examples/direct/reply.rs

Picking the right call

For a plain reply, session.reply(...) is the shortest path. For richer payloads (a Reference, explicit ids, file, embed, etc.), build the matching *Params and call the current session's send method:

Destination	Params	API method
Channel	MessageParams	ChannelReplySession::send_message
Direct message	DirectMessageParams	DirectReplySession::send_message
Group	GroupMessageParams	GroupReplySession::send_message
C2C	C2CMessageParams	C2CReplySession::send_message

// Quoted reply (channel) — see examples/guild/reply_reference.rs
let params = MessageParams {
    content: Some("<emoji:4>这是一条引用消息".to_string()),
    message_reference: Some(Reference { message_id: Some(message_id.clone()), ignore_get_message_error: None }),
    ..Default::default()
};
session.send_message(params).await?;

Reply sessions fill msg_id, event_id, and msg_seq automatically when you leave them unset. Direct messages need the DM guild_id from the inbound Message or a session created with BotApi::create_direct_message.
