Struct serenity::model::ChannelId

pub struct ChannelId(pub u64);

An identifier for a Channel

Methods

impl ChannelId

fn broadcast_typing(&self) -> Result<()>

Broadcasts that the current user is typing to a channel for the next 5 seconds.

After 5 seconds, another request must be made to continue broadcasting that the current user is typing.

This should rarely be used for bots, and should likely only be used for signifying that a long-running command is still being executed.

Note: Requires the Send Messages permission.

Examples

use serenity::model::ChannelId;

let _successful = ChannelId(7).broadcast_typing();

fn create_permission(&self, target: &PermissionOverwrite) -> Result<()>

Creates a permission overwrite for either a single Member or Role within the channel.

Refer to the documentation for GuildChannel::create_permission for more information.

Requires the Manage Channels permission.

fn create_reaction<M, R>(&self, message_id: M, reaction_type: R) -> Result<()> where
    M: Into<MessageId>,
    R: Into<ReactionType>,

Message::react may be a more suited method of reacting in most cases.

fn edit<F: FnOnce(EditChannel) -> EditChannel>(
    &self,
    f: F
) -> Result<GuildChannel>

use serenity::model::ChannelId;
use std::fs::File;

let channel_id = ChannelId(7);

let f1 = File::open("my_file.jpg").unwrap();
let f2 = File::open("my_file2.jpg").unwrap();

let files = vec![(&f1, "my_file.jpg"), (&f2, "my_file2.jpg")];
