Struct serenity::builder::ExecuteWebhook

pub struct ExecuteWebhook(pub HashMap<&'static str, Value>);

A builder to create the inner content of a Webhook's execution.

This is a structured way of cleanly creating the inner execution payload, to reduce potential argument counts.

Refer to the documentation for execute_webhook on restrictions with execution payloads and its fields.

Examples

Creating two embeds, and then sending them as part of the delivery payload of Webhook::execute:

use serenity::http::Http;
use serenity::model::channel::Embed;
use serenity::utils::Colour;

let id = 245037420704169985;
let token = "ig5AO-wdVWpCBtUUMxmgsWryqgsW3DChbKYOINftJ4DCrUbnkedoYZD0VOH1QLr-S3sV";
let webhook = http.as_ref().get_webhook_with_token(id, token)
    .expect("valid webhook");

let website = Embed::fake(|e| {
    e.title("The Rust Language Website")
        .description("Rust is a systems programming language.")
        .colour(Colour::from_rgb(222, 165, 132))
});

let resources = Embed::fake(|e| {
    e.title("Rust Resources")
        .description("A few resources to help with learning Rust")
        .colour(0xDEA584).field("The Rust Book", "A comprehensive resource for Rust.", false)
        .field("Rust by Example", "A collection of Rust examples", false)
});

let _ = webhook.execute(&http, false, |w| {
    w.content("Here's some information on Rust:").embeds(vec![website, resources])
});

Methods

impl ExecuteWebhook

pub fn avatar_url<S: ToString>(&mut self, avatar_url: S) -> &mut Self

Override the default avatar of the webhook with an image URL.

Examples

Overriding the default avatar:

let avatar_url = "https://i.imgur.com/KTs6whd.jpg";

let _ = webhook.execute(&http, false, |w| {
    w.avatar_url(avatar_url).content("Here's a webhook")
});

pub fn content<S: ToString>(&mut self, content: S) -> &mut Self

Set the content of the message.

Note that when setting at least one embed via embeds, this may be omitted.

Examples

Sending a webhook with a content of "foo":

let execution = webhook.execute(&http, false, |w| {
    w.content("foo")
});

if let Err(why) = execution {
    println!("Err sending webhook: {:?}", why);
}

pub fn embeds(&mut self, embeds: Vec<Value>) -> &mut Self

Set the embeds associated with the message.

This should be used in combination with Embed::fake, creating one or more fake embeds to send to the API.

Examples

Refer to the struct-level documentation for an example on how to use embeds.

pub fn tts(&mut self, tts: bool) -> &mut Self

Whether the message is a text-to-speech message.

Examples

Sending a webhook with text-to-speech enabled:

let execution = webhook.execute(&http, false, |w| {
    w.content("hello").tts(true)
});

if let Err(why) = execution {
    println!("Err sending webhook: {:?}", why);
}

pub fn username<S: ToString>(&mut self, username: S) -> &mut Self

Override the default username of the webhook.

Examples

Overriding the username to "hakase":

let execution = webhook.execute(&http, false, |w| {
    w.content("hello").username("hakase")
});

if let Err(why) = execution {
    println!("Err sending webhook: {:?}", why);
}

Trait Implementations

impl Clone for ExecuteWebhook

fn clone(&self) -> ExecuteWebhook

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExecuteWebhook

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for ExecuteWebhook

fn default() -> ExecuteWebhook

Returns a default set of values for a Webhook execution.

The only default value is tts being set to false.

Examples

Creating an ExecuteWebhook builder:

use serenity::builder::ExecuteWebhook;

let executor = ExecuteWebhook::default();
