Struct SubscribeFilter 

pub struct SubscribeFilter {
    pub event_types: Vec<String>,
    pub min_height: Option<u64>,
    pub max_height: Option<u64>,
    pub tx_hash: Option<String>,
}

Client-sent subscription filter for WebSocket events.

The client can send a JSON message to control which events are forwarded. If no filter is sent, all events are forwarded.

Fields

event_types: Vec<String>

Event types to receive (e.g. [“NewBlock”, “TxCommitted”, “EpochChange”]). If empty or absent, all event types are forwarded.

min_height: Option<u64>

Only forward events at or above this height (for NewBlock / TxCommitted).

max_height: Option<u64>

Only forward events at or below this height.

tx_hash: Option<String>

Only forward TxCommitted events matching this tx hash (hex).
