Function rate_limit_retry_after 

pub async fn rate_limit_retry_after(
    rl: &RequestRateLimit,
    retry_after_secs: u64,
)

Record a server-returned Retry-After delay.

Call this when the upstream API responds with HTTP 429 and a Retry-After header. Subsequent calls to rate_limit_acquire will block for at least secs seconds. A shorter secs value will never shorten an existing block.

Example

use stygian_graph::adapters::graphql_rate_limit::{
    RateLimitConfig, RequestRateLimit, rate_limit_retry_after,
};

let rl = RequestRateLimit::new(RateLimitConfig::default());
rate_limit_retry_after(&rl, 30).await;
