Struct async_txn::EntryRef

pub struct EntryRef<'a, K, V> {
    pub data: EntryDataRef<'a, K, V>,
    pub version: u64,
}

The reference of the Entry.

Fields

data: EntryDataRef<'a, K, V>

version: u64

Implementations

impl<'a, K, V> EntryRef<'a, K, V>

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

Get the key of the entry.

pub const fn value(&self) -> Option<&V>

Get the value of the entry, if None, it means the entry is removed.

pub const fn version(&self) -> u64

Returns the version of the entry.

This version is useful when you want to implement MVCC.

Trait Implementations

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

fn clone(&self) -> EntryRef<'a, K, V>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, K, V> Debug for EntryRef<'a, K, V>

where K: Debug, V: Debug,

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

Formats the value using the given formatter.

impl<'a, K, V> Hash for EntryRef<'a, 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)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a, K, V> PartialEq for EntryRef<'a, K, V>

where K: PartialEq, V: PartialEq,

fn eq(&self, other: &EntryRef<'a, K, V>) -> 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<'a, K, V> Eq for EntryRef<'a, K, V>

where K: Eq, V: Eq,
