Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

id: UserId

The unique Id of the user. Can be used to calculate the account’s creation date.

name: String

The account’s username. Changing username will trigger a discriminator change if the username+discriminator pair becomes non-unique. Unless the account has migrated to a next generation username, which does not have a discriminant.

discriminator: Option<NonZeroU16>

The account’s discriminator to differentiate the user from others with the same Self::name. The name+discriminator pair is always unique. If the discriminator is not present, then this is a next generation username which is implicitly unique.

global_name: Option<String>

The account’s display name, if it is set. For bots this is the application name.

avatar: Option<ImageHash>

Optional avatar hash.

bot: bool

Indicator of whether the user is a bot.

system: bool

Whether the user is an Official Discord System user (part of the urgent message system).

mfa_enabled: bool

Whether the user has two factor enabled on their account

banner: Option<ImageHash>

Optional banner hash.

Note: This will only be present if the user is fetched via Rest API, e.g. with crate::http::Http::get_user.

accent_colour: Option<Colour>

The user’s banner colour encoded as an integer representation of hexadecimal colour code

Note: This will only be present if the user is fetched via Rest API, e.g. with crate::http::Http::get_user.

locale: Option<String>

The user’s chosen language option

verified: Option<bool>

Whether the email on this account has been verified

Requires Scope::Email

email: Option<String>

The user’s email

Requires Scope::Email

flags: UserPublicFlags

The flags on a user’s account

premium_type: PremiumType

The type of Nitro subscription on a user’s account

public_flags: Option<UserPublicFlags>

The public flags on a user’s account

member: Option<Box<PartialMember>>

Only included in Message::mentions for messages from the gateway.

Discord docs.

Implementations

impl User

pub fn avatar_url(&self) -> Option<String>

Available on crate feature model only.

Returns the formatted URL of the user’s icon, if one exists.

This will produce a WEBP image URL, or GIF if the user has a GIF avatar.

pub fn banner_url(&self) -> Option<String>

Available on crate feature model only.

Returns the formatted URL of the user’s banner, if one exists.

This will produce a WEBP image URL, or GIF if the user has a GIF banner.

Note: This will only be present if the user is fetched via Rest API, e.g. with crate::http::Http::get_user.

pub async fn create_dm_channel( &self, cache_http: impl CacheHttp ) -> Result<PrivateChannel>

Available on crate feature model only.

Creates a direct message channel between the current user and the user. This can also retrieve the channel if one already exists.

Errors

See UserId::create_dm_channel for what errors may be returned.

pub fn created_at(&self) -> Timestamp

Available on crate feature model only.

Retrieves the time that this user was created at.

pub fn default_avatar_url(&self) -> String

Available on crate feature model only.

Returns the formatted URL to the user’s default avatar URL.

This will produce a PNG URL.

pub async fn direct_message( &self, cache_http: impl CacheHttp, builder: CreateMessage ) -> Result<Message>

Available on crate feature model only.

Sends a message to a user through a direct message channel. This is a channel that can only be accessed by you and the recipient.

Examples

See UserId::direct_message for examples.

Errors

See UserId::direct_message for errors.

pub async fn dm( &self, cache_http: impl CacheHttp, builder: CreateMessage ) -> Result<Message>

Available on crate feature model only.

This is an alias of Self::direct_message.

pub fn face(&self) -> String

Available on crate feature model only.

Retrieves the URL to the user’s avatar, falling back to the default avatar if needed.

This will call Self::avatar_url first, and if that returns None, it then falls back to Self::default_avatar_url.

pub fn static_face(&self) -> String

Available on crate feature model only.

Retrieves the URL to the static version of the user’s avatar, falling back to the default avatar if needed.

This will call Self::static_avatar_url first, and if that returns None, it then falls back to Self::default_avatar_url.

pub async fn has_role( &self, cache_http: impl CacheHttp, guild_id: impl Into<GuildId>, role: impl Into<RoleId> ) -> Result<bool>

Available on crate feature model only.

Check if a user has a Role. This will retrieve the Guild from the Cache if it is available, and then check if that guild has the given Role.

Examples

Check if a guild has a Role by Id:

// Assumes a 'guild_id' and `role_id` have already been bound
let _ = message.author.has_role(guild_id, role_id);

Errors

Returns an Error::Http if the given Guild is unavailable, if that Role does not exist in the given Guild, or if the given User is not in that Guild.

May also return an Error::Json if there is an error in deserializing the API response.

pub async fn refresh(&mut self, cache_http: impl CacheHttp) -> Result<()>

Available on crate feature model only.

Refreshes the information about the user.

Replaces the instance with the data retrieved over the REST API.

Errors

See UserId::to_user for what errors may be returned.

pub fn static_avatar_url(&self) -> Option<String>

Available on crate feature model only.

Returns a static formatted URL of the user’s icon, if one exists.

This will always produce a WEBP image URL.

pub fn tag(&self) -> String

Available on crate feature model only.

Returns the “tag” for the user.

The “tag” is defined as “username#discriminator”, such as “zeyla#5479”.

Examples

Make a command to tell the user what their tag is:

#[serenity::async_trait]
impl EventHandler for Handler {
    async fn message(&self, context: Context, msg: Message) {
        if msg.content == "!mytag" {
            let content = format!("Your tag is: {}", msg.author.tag());
            let _ = msg.channel_id.say(&context.http, &content).await;
        }
    }
}

pub async fn nick_in( &self, cache_http: impl CacheHttp, guild_id: impl Into<GuildId> ) -> Option<String>

Trait Implementations

impl ArgumentConvert for User

Available on crate features client and utils only.

2. Lookup by mention.
3. Lookup by name#discrim.
4. Lookup by name
