Struct perkv::RawKV

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

The type that represents a raw key-value store

Methods

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

pub fn new(p: &str, idxn: impl Into<Cow<'static, str>>) -> PRes<RawKV<K, V>>

Creates a new instance of the raw KV store

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

Inserts a key, value pair into the KV store

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

Gets the associated value from a key

pub fn remove(&self, key: K) -> PRes<()>

Removes a key and associated value from the KV store

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

Removes all entries from the KV store

pub fn iter(&self) -> PRes<impl Iterator<Item = (K, V)>>

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

pub fn keys(&self) -> PRes<impl Iterator<Item = K>>

Gets all the keys contained in the KV store

Trait Implementations

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

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.
