Represents a guild's text or voice channel. Some methods are available only for voice channels and some are only available for text channels.
Fields
id: ChannelId
The unique Id of the channel.
The default channel Id shares the Id of the guild and the default role.
bitrate: Option<u64>
The bitrate of the channel.
Note: This is only available for voice channels.
category_id: Option<ChannelId>
Whether this guild channel belongs in a category.
guild_id: GuildId
The Id of the guild the channel is located in.
If this matches with the id
, then this is the default text channel.
The original voice channel has an Id equal to the guild's Id, incremented by one.
kind: ChannelType
The type of the channel.
last_message_id: Option<MessageId>
The Id of the last message sent in the channel.
Note: This is only available for text channels.
last_pin_timestamp: Option<DateTime<FixedOffset>>
The timestamp of the time a pin was most recently made.
Note: This is only available for text channels.
name: String
The name of the channel.
permission_overwrites: Vec<PermissionOverwrite>
position: i64
The position of the channel.
The default text channel will almost always have a position of -1
or
0
.
topic: Option<String>
The topic of the channel.
Note: This is only available for text channels.
user_limit: Option<u64>
The maximum number of members allowed in the channel.
Note: This is only available for voice channels.
nsfw: bool
Used to tell if the channel is not safe for work.
Note however, it's recommended to use is_nsfw
as it's gonna be more accurate.
