Struct ItemRef

pub struct ItemRef<'a, K, V> {
    pub key: &'a K,
    pub value: &'a V,
    pub sequence: u64,
}

ItemRef is a struct that contains references to key and value, which is useful since in many cases since keys and values are stored separately so &Item is not possible.

Fields

key: &'a K

value: &'a V

sequence: u64

Implementations

impl<K: Clone, V: Clone> ItemRef<'_, K, V>

pub fn cloned(&self) -> Item<K, V>

pub fn boxed(&self) -> BoxedItem<K, V>

Trait Implementations

impl<'a, K, V> Clone for ItemRef<'a, K, V>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, K: Debug, V: Debug> Debug for ItemRef<'a, K, V>

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

Formats the value using the given formatter.

impl<'a, K, V> From<&'a Box<Item<K, V>>> for ItemRef<'a, K, V>

fn from(item: &'a BoxedItem<K, V>) -> ItemRef<'a, K, V>

Converts to this type from the input type.

impl<'a, K, V> From<&'a Item<K, V>> for ItemRef<'a, K, V>

fn from(item: &'a Item<K, V>) -> ItemRef<'a, K, V>

Converts to this type from the input type.

impl From<ItemRef<'_, AllocatorKeyV32, AllocatorValueV32>> for Allocation

fn from(item: ItemRef<'_, AllocatorKey, AllocatorValue>) -> Self

Converts to this type from the input type.

impl<K: Debug, V> From<ItemRef<'_, K, V>> for Key

fn from(item: ItemRef<'_, K, V>) -> Self

Converts to this type from the input type.

impl<K, V: Debug> From<ItemRef<'_, K, V>> for Value

fn from(item: ItemRef<'_, K, V>) -> Self

Converts to this type from the input type.

impl<'a> From<ItemRef<'a, ObjectKeyV43, ObjectValueV41>> for Option<(u64, u64, &'a ExtentKey, &'a ExtentValue)>

fn from(item: ItemRef<'a, ObjectKey, ObjectValue>) -> Self

Converts to this type from the input type.

impl<'a, K: PartialEq, V: PartialEq> PartialEq for ItemRef<'a, K, V>

fn eq(&self, other: &ItemRef<'a, 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<'a, K, V> Serialize for ItemRef<'a, K, V>

where K: Serialize, V: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
