Struct lumina_node::store::InMemoryStore

pub struct InMemoryStore { /* private fields */ }

A non-persistent in memory Store implementation.

Implementations

impl InMemoryStore

pub fn new() -> Self

Create a new store.

pub async fn async_clone(&self) -> Self

Clone the store and all its contents. Async fn due to internal use of async mutex.

impl Default for InMemoryStore

fn default() -> Self

Returns the “default value” for a type.
