Struct UpdateFollowup

pub struct UpdateFollowup<'a> { /* private fields */ }

Edit a followup message of an interaction, by its token and the message ID.

You can pass None to any of the methods to remove the associated field. Pass None to content to remove the content. You must ensure that the message still contains at least one of attachments, components, content, or embeds.

This endpoint is not bound to the application’s global rate limit.

Examples

Update a followup message by setting the content to test <@3> - attempting to mention user ID 3 - while specifying that no entities can be mentioned.

use std::env;
use twilight_http::Client;
use twilight_model::{channel::message::AllowedMentions, id::Id};

let client = Client::new(env::var("DISCORD_TOKEN")?);
let application_id = Id::new(1);

client
    .interaction(application_id)
    .update_followup("token here", Id::new(2))
    // By creating a default set of allowed mentions, no entity can be
    // mentioned.
    .allowed_mentions(Some(&AllowedMentions::default()))
    .content(Some("test <@3>"))
    .await?;

Implementations

impl<'a> UpdateFollowup<'a>

pub fn allowed_mentions( self, allowed_mentions: Option<&'a AllowedMentions>, ) -> Self

Specify the AllowedMentions for the message.

Unless otherwise called, the request will use the client’s default allowed mentions. Set to None to ignore this default.

pub fn attachments(self, attachments: &'a [Attachment]) -> Self

Attach multiple new files to the message.

This method clears previous calls.

Errors

Returns an error of type AttachmentDescriptionTooLarge if the attachments’ description is too large.

Returns an error of type AttachmentFilename if any filename is invalid.

pub fn components(self, components: Option<&'a [Component]>) -> Self

Set the message’s list of Components.

Calling this method will clear previous calls.

Editing

Pass None to clear existing components.

Errors

Refer to the errors section of twilight_validate::component::component for a list of errors that may be returned as a result of validating each provided component.

pub fn content(self, content: Option<&'a str>) -> Self

Set the message’s content.

The maximum length is 2000 UTF-16 characters.

Editing

Pass None to remove the message content. This is impossible if it would leave the message empty of attachments, content, or embeds.

Errors

Returns an error of type ContentInvalid if the content length is too long.

pub fn embeds(self, embeds: Option<&'a [Embed]>) -> Self

Set the message’s list of embeds.

Calling this method will clear previous calls.

The amount of embeds must not exceed EMBED_COUNT_LIMIT. The total character length of each embed must not exceed EMBED_TOTAL_LENGTH characters. Additionally, the internal fields also have character limits. See Discord Docs/Embed Limits.

Editing

To keep all embeds, do not call this method. To modify one or more embeds in the message, acquire them from the previous message, mutate them in place, then pass that list to this method. To remove all embeds, pass None. This is impossible if it would leave the message empty of attachments, content, or embeds.

Examples

Create an embed and update the message with the new embed. The content of the original message is unaffected and only the embed(s) are modified.

use twilight_http::Client;
use twilight_model::id::Id;
use twilight_util::builder::embed::EmbedBuilder;

let client = Client::new("token".to_owned());
let application_id = Id::new(1);
let message_id = Id::new(2);

let embed = EmbedBuilder::new()
    .description(
        "Powerful, flexible, and scalable ecosystem of Rust \
    libraries for the Discord API.",
    )
    .title("Twilight")
    .url("https://twilight.rs")
    .validate()?
    .build();

client
    .interaction(application_id)
    .update_followup("token", message_id)
    .embeds(Some(&[embed]))
    .await?;

Errors

Returns an error of type TooManyEmbeds if there are too many embeds.

Otherwise, refer to the errors section of twilight_validate::embed::embed for a list of errors that may occur.

pub fn keep_attachment_ids( self, attachment_ids: &'a [Id<AttachmentMarker>], ) -> Self

Specify multiple Id<AttachmentMarker>s already present in the target message to keep.

If called, all unspecified attachments (except ones added with attachments) will be removed from the message. This is impossible if it would leave the message empty of attachments, content, or embeds. If not called, all attachments will be kept.

pub fn payload_json(self, payload_json: &'a [u8]) -> Self

JSON encoded body of any additional request fields.

If this method is called, all other fields are ignored, except for attachments. See Discord Docs/Uploading Files.

Examples

See ExecuteWebhook::payload_json for examples.
