Struct StdbSubscriptions 

Source 
pub struct StdbSubscriptions<K, M>
where
    K: Eq + Hash + Clone + Send + Sync + 'static,
    M: SpacetimeModule,
    M::SubscriptionHandle: StdbSubscriptionHandle + Send + Sync + 'static,
{ /* private fields */ }
Expand description

SpacetimeDB subscription Resource.

Keeps subscription intent separate from active handles so queued queries can be reapplied after reconnects.

Source§

impl<K, M> StdbSubscriptions<K, M>
where K: Eq + Hash + Clone + Send + Sync + 'static, M: SpacetimeModule, M::SubscriptionHandle: StdbSubscriptionHandle + Send + Sync + 'static,

Source

pub fn subscribe_query<T, Q>( &mut self, key: K, query: impl Fn(M::QueryBuilder) -> Q, )
where Q: Query<T>,

Stores a typed query for key and queues it to be applied.

Source

pub fn subscribe_sql(&mut self, key: K, sql: impl Into<String>)

Source

pub fn unsubscribe(&mut self, key: &K) -> StdbResult<()>

Unsubscribes key and removes its stored query.

Source

pub fn unsubscribe_all(&mut self) -> StdbResult<()>

Unsubscribes all active handles and clears all stored queries.

Returns the first unsubscribe error, if any.

Source

pub fn sql_for(&self, key: &K) -> Option<&str>

Source

pub fn is_queued(&self, key: &K) -> bool

Returns true if key has queued subscription work.

Source

pub fn is_active(&self, key: &K) -> bool

Returns true if key has an active subscription handle.
