pub const fn key(&self) -> &K

Returns the key.

pub const fn version(&self) -> u64

Returns the version of the key.

pub fn set_version(&mut self, version: u64)

Set the version of the key.

pub const fn with_version(self, version: u64) -> Key<K>

Set the version of the key.

pub fn into_components(self) -> (K, u64)

Consumes the key and returns the key and the version.

Trait Implementations

impl<K> Borrow<K> for Key<K>

fn borrow(&self) -> &K

Immutably borrows from an owned value.

impl<K> Clone for Key<K>

where K: Clone,

fn clone(&self) -> Key<K>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K> Debug for Key<K>

where K: Debug,

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

Formats the value using the given formatter.

impl<K> Hash for Key<K>

where K: Hash,

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

where __H: Hasher,

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<K> Ord for Key<K>

where K: Ord,

fn cmp(&self, other: &Key<K>) -> 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<K> PartialEq for Key<K>

where K: PartialEq,

fn eq(&self, other: &Key<K>) -> 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<K> PartialOrd for Key<K>

where K: Ord,

fn partial_cmp(&self, other: &Key<K>) -> 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.
