    pub channel: GuildChannel,
}
Expand description

Fields§

§message: Message

The message to preview.

§channel: GuildChannel

The channel containing the message.

Implementations§

Source§

impl Preview

Source

async fn get( args: &MessageLinkIDs, ctx: &Context, source_channel: &GuildChannel, ) -> Result<Preview, PreviewError>

Retrieves a preview for the given message link.

Validates that the linked channel is not NSFW, is not a private thread or DM, and that everyone who can view the request’s source_channel could also view the linked channel. The expanded content is posted as a single message that all members of source_channel can read, so the linked channel must be at least as visible as the source channel to avoid leaking restricted content. Public and news threads are judged by their parent channel’s permissions, since threads do not carry their own overwrites.

When the link target is the same channel as source_channel, the visibility checks are skipped entirely: the reply lands in that same channel, so it cannot expose anything its readers cannot already see.
