Struct persawkv::BaseKV

pub struct BaseKV<K, V>(_, _, _, _);

The type that represents a key--(value mode generic)-value store

Methods

impl<K, V> BaseKV<K, V> where
    K: IndexType,
    V: IndexType, 

pub fn new(
    p: &str,
    idxn: impl Into<Cow<'static, str>>,
    vm: ValueMode
) -> PRes<Self>

Creates a new instance of the value-mode-generic KV store

pub fn with_backend(
    persy: Persy,
    idxn: impl Into<Cow<'static, str>>,
    vm: ValueMode
) -> PRes<Self>

Creates a new instance of the value-mode-generic KV store with the specified Persy instance as backend

pub fn get(&self, key: &K) -> PRes<Option<Value<V>>>

Gets the associated value from a key

pub fn iter(&self) -> PRes<Iter<K, V>>

Returns an iterator visiting all key-value pairs in arbitrary order

pub fn range<R>(&self, r: R) -> PRes<Iter<K, V>> where
    R: RangeBounds<K>, 

Returns an iterator visiting all key-value pairs inside the specified range in arbitrary order

Trait Implementations

impl<K, V> KV<K, V> for BaseKV<K, V> where
    K: IndexType,
    V: IndexType, 

fn clear(&self) -> PRes<()>

Removes all entries from the KV store

fn insert(&self, key: K, value: V) -> PRes<()>

Inserts a key, value pair into the KV store

fn keys(&self) -> PRes<KeysIter<K, V>>

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

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
