Struct Storage

pub struct Storage<K, V> { /* private fields */ }

A thread-safe key-value storage using DashMap.

Examples

use kvdb_lib::Storage;

let storage = Storage::new(); storage.set(1, “value1”);

assert_eq!(storage.get(&1), Some(“value1”));

Implementations

impl<K, V> Storage<K, V>

where K: Eq + Hash + Clone + Copy, V: Clone + Copy,

pub fn new() -> Self

Creates a new, empty Storage.

Examples

use kvdb_lib::Storage;

let storage: Storage<i32, &str> = Storage::new();

pub fn set(&self, key: K, value: V)

Inserts a key-value pair into the storage.

If the storage did not have this key present, None is returned. If the storage did have this key present, the value is updated, and the old value is returned.

Examples

use kvdb_lib::Storage;

let storage = Storage::new(); storage.set(1, “value1”);

assert_eq!(storage.get(&1), Some(“value1”));

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

Retrieves a value from the storage, given a key.

Examples

use kvdb_lib::Storage;

let storage = Storage::new(); storage.set(1, “value1”);

assert_eq!(storage.get(&1), Some(“value1”));

pub fn get_all(&self) -> Vec<(K, V)>

Retrieves all key-value pairs from the storage as a vector of tuples.

Examples

use kvdb_lib::Storage;

let storage = Storage::new();

storage.set(1, “value1”); storage.set(2, “value2”); let all = storage.get_all();

assert_eq!(all.len(), 2); assert!(all.contains(&(1, “value1”))); assert!(all.contains(&(2, “value2”)));

pub fn remove(&self, key: K)

Removes a key-value pair from the storage.

Examples

use kvdb_lib::Storage;

let storage = Storage::new();

storage.set(1, “value1”); storage.remove(1);

assert_eq!(storage.get(&1), None);
