serenity-utils

A library to provide conversions, prompts and menu functionality for Discord bots created with serenity.

This library provides implementations to easily:

Convert a string to serenity's guild-specific models.
Get user response using message or reaction prompts.
Display paginated reaction-based messages/menus.
Format text in different ways before sending.
Create embeds and messages with field access.

Installation and Usage

To use this crate, add the following to your Cargo.toml:

[dependencies]
serenity_utils = "0.4.0"

Note: This crate only supports serenity's async versions and a minimum of Rust 1.39.

Examples

Here are a few examples to use some of serenity_utils's features.

Reaction Prompt

use serenity::{
   model::prelude::{ChannelId, Message, ReactionType},
   prelude::Context,
};
use serenity_utils::{prompt::reaction_prompt, Error};

async fn prompt(ctx: &Context, msg: &Message) -> Result<(), Error> {
    // Emojis for the prompt.
    let emojis = [
        ReactionType::from('🐶'),
        ReactionType::from('🐱'),
    ];

    let prompt_msg = ChannelId(7).say(&ctx.http, "Dogs or cats?").await?;

    // Creates the prompt and returns the result. Because of `reaction_prompt`'s
    // return type, you can use the `?` operator to get the result.
    // The `Ok()` value is the selected emoji's index (wrt the `emojis` slice)
    // and the emoji itself. We don't require the emoji here, so we ignore it.
    let (idx, _) = reaction_prompt(
        ctx,
        &prompt_msg,
        &msg.author,
        &emojis,
        30.0
    )
    .await?;

    if idx == 0 {
        // Dogs!
    } else {
        // Cats!
    }

    Ok(())
}

use serenity::{
    builder::CreateMessage,
    model::prelude::Message,
    prelude::Context,
};
use serenity_utils::{
    menu::{Menu, MenuOptions},
    Error,
};

async fn use_menu(ctx: &Context, msg: &Message) -> Result<(), Error> {
    let mut page_one = CreateMessage::default();
    page_one
        .content("Page number one!")
        .embed(|e| {
            e.description("The first page!");

            e
        });

    let mut page_two = CreateMessage::default();
    page_two
        .content("Page number two!")
        .embed(|e| {
            e.description("The second page!");

            e
        });

    let pages = [page_one, page_two];

    // Creates a new menu.
    let menu = Menu::new(ctx, msg, &pages, MenuOptions::default());

    // Runs the menu and returns optional `Message` used to display the menu.
    let opt_message = menu.run().await?;

    Ok(())
}

Features

Some functionality of this crate is dependent on serenity's features.

The following serenity features are required when using serenity_utils:

client
collector
gateway
model

The following serenity_utils features are optional:

cache: It is required to get Member from user name, tag or nickname when using the Conversion trait.
rustls_backend: Uses Rustls for all platforms, a pure Rust implementation.
native_tls_backend: Uses SChannel on Windows, Secure Transport on macOS, and OpenSSL on other platforms.

They enable serenity's features with the same names.

Note: One of rustls_backend and native_tls_backend must be used.

cache and rustls_backend are enabled by default.

You can specify features by adding this to your Cargo.toml:

[dependencies.serenity_utils]
version = "0.4.0"

# To disable default features.
default-features = false

# Choose features you need.
features = ["cache", "native_tls_backend"]
