Struct MemoryStorage 

pub struct MemoryStorage { /* private fields */ }

In-memory storage backend (no persistence)

Stores data in a HashMap in memory. Data is lost when the instance is dropped. This is useful for:

• Testing
• Temporary data
• Performance-critical scenarios where persistence isn’t needed

Thread Safety

MemoryStorage is thread-safe and can be shared across threads using Arc<MemoryStorage>.

Example

use gun::storage::{Storage, MemoryStorage};
use gun::state::Node;
use std::sync::Arc;

let storage = Arc::new(MemoryStorage::new());
let node = Node::with_soul("user_123".to_string());
storage.put("user_123", &node).await?;

Implementations

impl MemoryStorage

pub fn new() -> Self

Trait Implementations

impl Default for MemoryStorage

fn default() -> Self

Returns the “default value” for a type.

impl Storage for MemoryStorage

fn get<'life0, 'life1, 'async_trait>( &'life0 self, soul: &'life1 str, ) -> Pin<Box<dyn Future<Output = GunResult<Option<Node>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve a node by its soul (unique identifier)

fn put<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, soul: &'life1 str, node: &'life2 Node, ) -> Pin<Box<dyn Future<Output = GunResult<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store a node by its soul (unique identifier)

fn has<'life0, 'life1, 'async_trait>( &'life0 self, soul: &'life1 str, ) -> Pin<Box<dyn Future<Output = GunResult<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Check if a node exists in storage
