Struct Entry

pub struct Entry<K, V> {
    pub version: u64,
    pub data: EntryData<K, V>,
}

An entry can be persisted to the database.

Fields

version: u64

The version of the entry.

data: EntryData<K, V>

The data of the entry.

Implementations

impl<K, V> Entry<K, V>

pub const fn data(&self) -> &EntryData<K, V>

Returns the data contained by the entry.

pub const fn version(&self) -> u64

Returns the version (can also be tought as transaction timestamp) of the entry.

pub fn into_components(self) -> (u64, EntryData<K, V>)

Consumes the entry and returns the version and the entry data.

pub fn key(&self) -> &K

Returns the key of the entry.

pub fn split(self) -> (K, EntryValue<V>)

Split the entry into its key and EntryValue.

pub fn unsplit(key: K, value: EntryValue<V>) -> Entry<K, V>

Unsplit the key and EntryValue into an entry.

Trait Implementations

Returns a copy of the value.

impl<K, V> Clone for Entry<K, V>

where K: Clone, V: Clone,

fn clone(&self) -> Entry<K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K, V> Debug for Entry<K, V>

where K: Debug, V: Debug,

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

Formats the value using the given formatter.

impl<K, V> Hash for Entry<K, V>

where K: Hash, V: 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)

impl<K, V> Ord for Entry<K, V>

where K: Ord, V: Eq,

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

where K: PartialEq, V: PartialEq,

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

where K: Ord, V: Eq,

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

impl<K, V> Eq for Entry<K, V>

where K: Eq, V: Eq,
