Struct SubscriptionConfig 

pub struct SubscriptionConfig {
    pub entity_types: Vec<String>,
    pub events: Vec<SubscriptionEvent>,
    pub from_block: Option<u64>,
    pub buffer_size: usize,
}

Configuration for real-time entity change subscriptions.

Describes which entity types and events a subscriber is interested in. The actual WebSocket transport is not implemented here — this struct is carried as metadata for higher-level subscription routers.

Fields

entity_types: Vec<String>

Entity types to subscribe to (empty = all types).

events: Vec<SubscriptionEvent>

Event kinds to receive.

from_block: Option<u64>

Optional filter: only emit events at or above this block number.

buffer_size: usize

Maximum number of buffered events before backpressure is applied.
