Struct icu_provider::DataKeyHash

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

A compact hash of a DataKey. Useful for keys in maps.

The hash will be stable over time within major releases.

Implementations

impl DataKeyHash

pub const fn to_bytes(self) -> [u8; 4]

Gets the hash value as a byte array.

Trait Implementations

impl AsULE for DataKeyHash

type ULE = DataKeyHash

The ULE type corresponding to Self.

fn to_unaligned(self) -> Self::ULE

Converts from Self to Self::ULE.

fn from_unaligned(unaligned: Self::ULE) -> Self

Converts from Self::ULE to Self.

impl Clone for DataKeyHash

fn clone(&self) -> DataKeyHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataKeyHash

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

Formats the value using the given formatter.

impl Hash for DataKeyHash

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 DataKeyHash

fn cmp(&self, other: &DataKeyHash) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DataKeyHash

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for DataKeyHash

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl ULE for DataKeyHash

fn validate_byte_slice(bytes: &[u8]) -> Result<(), ZeroVecError>

Validates a byte slice, &[u8].

fn parse_byte_slice(bytes: &[u8]) -> Result<&[Self], ZeroVecError>

Parses a byte slice, &[u8], and return it as &[Self] with the same lifetime.

unsafe fn from_byte_slice_unchecked(bytes: &[u8]) -> &[Self]

Takes a byte slice, &[u8], and return it as &[Self] with the same lifetime, assuming that this byte slice has previously been run through Self::parse_byte_slice() with success.

fn as_byte_slice(slice: &[Self]) -> &[u8]

Given &[Self], returns a &[u8] with the same lifetime.

impl<'a> ZeroMapKV<'a> for DataKeyHash

type Container = ZeroVec<'a, DataKeyHash>

The container that can be used with this type: ZeroVec or VarZeroVec.

type Slice = ZeroSlice<DataKeyHash>

type GetType = <DataKeyHash as AsULE>::ULE

The type produced by Container::get()

type OwnedType = DataKeyHash

The type produced by Container::replace() and Container::remove(), also used during deserialization. If Self is human readable serialized, deserializing to Self::OwnedType should produce the same value once passed through Self::owned_as_self()
