MemoryStorage

Struct MemoryStorage 

Source
pub struct MemoryStorage { /* private fields */ }
Expand description

An in-process, non-persistent StateStorage backed by DashMap.

State is lost on process restart. Suitable for development and bots that do not need persistence.

MemoryStorage is Send + Sync + Clone - each clone shares the same underlying map, so you can hold an Arc<MemoryStorage> or clone freely.
