Struct InMemoryStore 

pub struct InMemoryStore<T: Clone + Send + Sync> { /* private fields */ }

Generic in-memory store for entities

This store provides a simple key-value storage with soft delete support. It’s designed for testing and prototyping, not for production use.

Type Parameters

• T: The entity type to store. Must be Clone + Send + Sync.

Implementations

impl<T: Clone + Send + Sync> InMemoryStore<T>

pub fn new() -> Self

Create a new empty in-memory store

pub fn new_shared() -> Arc<Self>

Create a new store wrapped in Arc for sharing across async tasks

pub async fn insert(&self, id: String, item: T)

Insert or update an item

pub async fn get(&self, id: &str) -> Option<T>

Get an item by ID (returns None if not found or soft-deleted)

pub async fn get_deleted(&self, id: &str) -> Option<T>

Get a soft-deleted item by ID

pub async fn exists(&self, id: &str) -> bool

Check if an item exists (excluding soft-deleted)

pub async fn exists_in_trash(&self, id: &str) -> bool

Check if an item exists in trash

pub async fn update(&self, id: &str, item: T) -> Option<T>

Update an existing item (returns None if not found)

pub async fn remove(&self, id: &str) -> Option<T>

Remove an item permanently (hard delete)

pub async fn soft_delete(&self, id: &str) -> bool

Soft delete an item (move to trash)

pub async fn restore(&self, id: &str) -> Option<T>

Restore a soft-deleted item from trash

pub async fn hard_delete(&self, id: &str) -> Option<T>

Permanently delete an item from trash

pub async fn empty_trash(&self) -> u64

Empty the trash (permanently delete all soft-deleted items)

pub async fn list(&self, page: u32, limit: u32) -> (Vec<T>, u64)

List items with pagination

Arguments

• page: Page number (1-indexed)
• limit: Items per page

Returns

Tuple of (items, total_count)

pub async fn list_deleted(&self, page: u32, limit: u32) -> (Vec<T>, u64)

List soft-deleted items with pagination

pub async fn all(&self) -> Vec<T>

Get all items (no pagination)

pub async fn all_deleted(&self) -> Vec<T>

Get all soft-deleted items

pub async fn count(&self) -> u64

Get the count of active items

pub async fn trash_count(&self) -> u64

Get the count of soft-deleted items

pub async fn clear(&self)

Clear all items (both active and deleted)

pub async fn clear_active(&self)

Clear only active items

pub async fn ids(&self) -> Vec<String>

Get all IDs of active items

pub async fn trash_ids(&self) -> Vec<String>

Get all IDs of soft-deleted items

Trait Implementations

impl<T: Clone + Send + Sync> Default for InMemoryStore<T>

fn default() -> Self

Returns the “default value” for a type.
