Struct serenity::model::channel::MessagesIter

pub struct MessagesIter<H: AsRef<Http>> { /* fields omitted */ }

A helper class returned by ChannelId::messages_iter

Implementations

impl<H: AsRef<Http>> MessagesIter<H>

pub fn stream(
    http: impl AsRef<Http>,
    channel_id: ChannelId
) -> impl Stream<Item = Result<Message>>

Streams over all the messages in a channel.

This is accomplished and equivalent to repeated calls to messages. A buffer of at most 100 messages is used to reduce the number of calls. necessary.

The stream returns the newest message first, followed by older messages.

Examples

use serenity::model::channel::MessagesIter;
use serenity::futures::StreamExt;

let mut messages = MessagesIter::<Http>::stream(&ctx, channel_id).boxed();
while let Some(message_result) = messages.next().await {
    match message_result {
        Ok(message) => println!(
            "{} said \"{}\"",
            message.author.name,
            message.content,
        ),
        Err(error) => eprintln!("Uh oh! Error: {}", error),
    }
}
