Struct StateStorage 

pub struct StateStorage { /* private fields */ }

Thread-safe, type-erased key-value store for sharing state between handlers.

Backed by a DashMap so reads never block writes. Thread-safe, type-keyed store for sharing data across handlers.

Values are stored by their TypeId so each type occupies exactly one slot. Use this for things that are global to the bot — database pools, configuration, shared counters.

StateStorage is cheap to clone (internally Arc-backed) and reads never block writes.

Example

use rustigram_bot::state::StateStorage;

let store = StateStorage::new();
store.insert(42_u32);
store.insert(my_db_pool);

let n: u32 = store.get().unwrap(); // 42

Implementations

impl StateStorage

pub fn new() -> Self

Creates a new empty StateStorage.

pub fn insert<T: Any + Send + Sync + 'static>(&self, value: T)

Inserts a value. Replaces any existing value of the same type.

pub fn get<T: Any + Send + Sync + Clone + 'static>(&self) -> Option<T>

Returns a clone of the stored value for type T, if present.

pub fn get_arc<T: Any + Send + Sync + 'static>(&self) -> Option<Arc<T>>

Returns an Arc reference to the stored value for type T.

Trait Implementations

impl Clone for StateStorage

fn clone(&self) -> StateStorage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for StateStorage

fn default() -> StateStorage

Returns the “default value” for a type.
