Expand description

Builder for a Polygon WebSocket stream.

Implementations§

Source§

impl PolygonStreamBuilder

Source

pub fn cluster(self, cluster: Cluster) -> Self

Set the cluster (asset class) to connect to.

Source

pub fn subscribe(self, channels: &[&str]) -> Self

Add subscription channels.

Channel prefixes:

  • T.* — Trades (e.g., "T.AAPL")
  • Q.* — Quotes (e.g., "Q.AAPL")
  • A.* — Per-second aggregates (e.g., "A.AAPL")
  • AM.* — Per-minute aggregates (e.g., "AM.AAPL")
Source

pub async fn build(self) -> Result<PolygonStream>

Connect and return a PolygonStream.
