pub async fn check_gateways(
reference: &str,
gateway_urls: &[String],
timeout: Duration,
) -> Result<Vec<GatewayResult>>Expand description
Probe public Swarm gateways via HEAD {gateway}/bzz/{ref} in
parallel. Mirrors the BYO-Bee philosophy: gateway results
complement (don’t replace) the vantage probes and aggregate into
the same top-level status.
