Struct twilight_model::id::Id

pub struct Id<T> { /* private fields */ }

ID of a resource, such as the ID of a channel or user.

Markers themselves perform no logical action, and are only used to ensure that IDs of incorrect types aren’t used. Read the marker documentation for additional information.

serde

This ID deserializes from both integers and strings and serializes into a string.

Implementations

impl<T> Id<T>

pub const fn new(n: u64) -> Self

Create a new ID, panicking if the value is zero.

This is primarily useful in const contexts where you are passing a hardcoded value.

Refer to new_checked for a checked alternative to this method.

Examples

use twilight_model::id::{marker::GenericMarker, Id};

const ID: Id<GenericMarker> = Id::new(123);

println!("id: {}", ID);

Panics

Panics if the value is 0.

pub const unsafe fn new_unchecked(n: u64) -> Self

Create a non-zero application ID without checking the value.

Equivalent to NonZeroU64::new_unchecked.

Safety

The value must not be zero.

pub const fn new_checked(n: u64) -> Option<Self>

Create a non-zero application ID, checking if the provided value is zero.

Examples

use twilight_model::id::{marker::GenericMarker, Id};

assert!(Id::<GenericMarker>::new_checked(123).is_some());
assert!(Id::<GenericMarker>::new_checked(0).is_none());

Equivalent to NonZeroU64::new.

pub const fn get(self) -> u64

Return the inner primitive value.

Equivalent to NonZeroU64::get.

Examples

Create an ID with a value and then confirm its inner value:

use twilight_model::id::{marker::ChannelMarker, Id};

let channel_id = Id::<ChannelMarker>::new(7);

assert_eq!(7, channel_id.get());

pub const fn cast<New>(self) -> Id<New>

Cast an ID from one type to another.

Examples

Cast a role ID to a guild ID, useful for the @everyone role:

use twilight_model::id::{marker::{GuildMarker, RoleMarker}, Id};

let role_id: Id<RoleMarker> = Id::new(1);

let guild_id: Id<GuildMarker> = role_id.cast();
assert_eq!(1, guild_id.get());
