Struct DiscriminatorDisplay

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

Display formatter for a user discriminator.

When formatted this will pad a discriminator with zeroes.

This may be preferable to use instead of using format! to avoid a String allocation, and may also be preferable to use rather than defining your own implementations via format_args!("{discriminator:04}").

Examples

Display the discriminator value 16 as a string:

use twilight_model::user::DiscriminatorDisplay;

let display = DiscriminatorDisplay::new(16);
assert_eq!("0016", display.to_string());

Implementations

impl DiscriminatorDisplay

pub const fn new(discriminator: u16) -> Self

Create a new display formatter for a discriminator.

Examples

Display the discriminator value 5 as a string:

use twilight_model::user::DiscriminatorDisplay;

let display = DiscriminatorDisplay::new(5);
assert_eq!("0005", display.to_string());

pub const fn get(self) -> u16

Retrieve the inner discriminator value.

Trait Implementations

impl Clone for DiscriminatorDisplay

fn clone(&self) -> DiscriminatorDisplay

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DiscriminatorDisplay

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

Formats the value using the given formatter.

impl Display for DiscriminatorDisplay

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

Formats the value using the given formatter.

impl Hash for DiscriminatorDisplay

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DiscriminatorDisplay

fn eq(&self, other: &DiscriminatorDisplay) -> 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.
