Struct DataMarkerId

pub struct DataMarkerId { /* private fields */ }

The ID of a data marker.

This is generally a DataMarkerIdHash. If debug assertions or the export Cargo feature are enabled, this also contains a human-readable string for an improved Debug implementation.

Implementations

impl DataMarkerId

pub const fn hashed(self) -> DataMarkerIdHash

Gets a platform-independent hash of a DataMarkerId.

The hash is 4 bytes and allows for fast comparison.

Example

use icu_provider::prelude::*;

icu_provider::data_marker!(FooV1, &'static str);

assert_eq!(FooV1::INFO.id.hashed().to_bytes(), [198, 217, 86, 48]);

Trait Implementations

impl Clone for DataMarkerId

fn clone(&self) -> DataMarkerId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataMarkerId

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

Formats the value using the given formatter.

impl Hash for DataMarkerId

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 Ord for DataMarkerId

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DataMarkerId

fn eq(&self, other: &Self) -> 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 PartialOrd for DataMarkerId

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
