Struct EmbedBuilder

pub struct EmbedBuilder(/* private fields */);

Available on crate feature builder only.

Create an [Embed] with a builder.

Examples

Build a simple embed:

use twilight_util::builder::embed::{EmbedBuilder, EmbedFieldBuilder};

let embed = EmbedBuilder::new()
    .description("Here's a list of reasons why Twilight is the best pony:")
    .field(EmbedFieldBuilder::new("Wings", "She has wings.").inline())
    .field(
        EmbedFieldBuilder::new("Horn", "She can do magic, and she's really good at it.")
            .inline(),
    )
    .validate()?
    .build();

Build an embed with an image:

use twilight_util::builder::embed::{EmbedBuilder, ImageSource};

let embed = EmbedBuilder::new()
    .description("Here's a cool image of Twilight Sparkle")
    .image(ImageSource::attachment("bestpony.png")?)
    .validate()?
    .build();

Implementations

impl EmbedBuilder

pub fn new() -> Self

Create a new embed builder.

pub fn build(self) -> Embed

Build this into an embed.

pub fn validate(self) -> Result<Self, EmbedValidationError>

Ensure the embed is valid.

Errors

Refer to the documentation of [twilight_validate::embed::embed] for possible errors.

pub fn author(self, author: impl Into<EmbedAuthor>) -> Self

Set the author.

Examples

Create an embed author:

use twilight_util::builder::embed::{EmbedAuthorBuilder, EmbedBuilder};

let author = EmbedAuthorBuilder::new("Twilight")
    .url("https://github.com/twilight-rs/twilight")
    .build();

let embed = EmbedBuilder::new().author(author).validate()?.build();

pub const fn color(self, color: u32) -> Self

Set the color.

This must be a valid hexadecimal RGB value. Refer to COLOR_MAXIMUM for the maximum acceptable value.

Examples

Set the color of an embed to 0xfd69b3:

use twilight_util::builder::embed::EmbedBuilder;

let embed = EmbedBuilder::new()
    .color(0xfd_69_b3)
    .description("a description")
    .validate()?
    .build();

pub fn description(self, description: impl Into<String>) -> Self

Set the description.

Refer to DESCRIPTION_LENGTH for the maximum number of UTF-16 code points that can be in a description.

Examples

use twilight_util::builder::embed::EmbedBuilder;

let embed = EmbedBuilder::new()
    .description("this is an embed")
    .validate()?
    .build();

pub fn field(self, field: impl Into<EmbedField>) -> Self

Add a field to the embed.

Examples

use twilight_util::builder::embed::{EmbedBuilder, EmbedFieldBuilder};

let embed = EmbedBuilder::new()
    .description("this is an embed")
    .field(EmbedFieldBuilder::new("a field", "and its value"))
    .validate()?
    .build();

pub fn footer(self, footer: impl Into<EmbedFooter>) -> Self

Set the footer of the embed.

Examples

use twilight_util::builder::embed::{EmbedBuilder, EmbedFooterBuilder};

let embed = EmbedBuilder::new()
    .description("this is an embed")
    .footer(EmbedFooterBuilder::new("a footer"))
    .validate()?
    .build();

pub fn image(self, image_source: ImageSource) -> Self

Set the image.

Examples

Set the image source to a URL:

use twilight_util::builder::embed::{EmbedBuilder, EmbedFooterBuilder, ImageSource};

let source =
    ImageSource::url("https://raw.githubusercontent.com/twilight-rs/twilight/main/logo.png")?;
let embed = EmbedBuilder::new()
    .footer(EmbedFooterBuilder::new("twilight"))
    .image(source)
    .validate()?
    .build();

pub fn thumbnail(self, image_source: ImageSource) -> Self

Add a thumbnail.

Examples

Set the thumbnail to an image attachment with the filename "twilight.png":

use twilight_util::builder::embed::{EmbedBuilder, ImageSource};

let embed = EmbedBuilder::new()
    .description("a picture of twilight")
    .thumbnail(ImageSource::attachment("twilight.png")?)
    .validate()?
    .build();

pub const fn timestamp(self, timestamp: Timestamp) -> Self

Set the ISO 8601 timestamp.

pub fn title(self, title: impl Into<String>) -> Self

Set the title.

Refer to TITLE_LENGTH for the maximum number of UTF-16 code points that can be in a title.

Examples

Set the title to “twilight”:

use twilight_util::builder::embed::EmbedBuilder;

let embed = EmbedBuilder::new()
    .title("twilight")
    .url("https://github.com/twilight-rs/twilight")
    .validate()?
    .build();

pub fn url(self, url: impl Into<String>) -> Self

Set the URL.

Examples

Set the URL to twilight’s repository:

use twilight_util::builder::embed::{EmbedBuilder, EmbedFooterBuilder};

let embed = EmbedBuilder::new()
    .description("twilight's repository")
    .url("https://github.com/twilight-rs/twilight")
    .validate()?
    .build();

Trait Implementations

impl Clone for EmbedBuilder

fn clone(&self) -> EmbedBuilder

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for EmbedBuilder

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

Formats the value using the given formatter.

impl Default for EmbedBuilder

fn default() -> Self

Create an embed builder with a default embed.

All embeds have a “rich” type.

impl From<Embed> for EmbedBuilder

fn from(value: Embed) -> Self

Converts to this type from the input type.

impl PartialEq for EmbedBuilder

fn eq(&self, other: &EmbedBuilder) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFrom<EmbedBuilder> for Embed

fn try_from(builder: EmbedBuilder) -> Result<Self, Self::Error>

Convert an embed builder into an embed, validating its contents.

This is equivalent to calling EmbedBuilder::validate, then EmbedBuilder::build.

type Error = EmbedValidationError

The type returned in the event of a conversion error.

impl Eq for EmbedBuilder

impl StructuralPartialEq for EmbedBuilder
