A crate for parsing HTTP rate limit headers as per the IETF draft

Last update: Jul 9, 2022

Overview

rate-limits

A crate for parsing HTTP rate limit headers as per the IETF draft. Inofficial implementations like the Github rate limit headers are also supported on a best effort basis. See vendor list for support.

use indoc::indoc;
use time::{OffsetDateTime, Duration};
use rate_limits::{Vendor, RateLimit, ResetTime};

let headers = indoc! {"
    x-ratelimit-limit: 5000
    x-ratelimit-remaining: 4987
    x-ratelimit-reset: 1350085394
"};

assert_eq!(
    RateLimit::new(headers).unwrap(),
    RateLimit {
        limit: 5000,
        remaining: 4987,
        reset: ResetTime::DateTime(
            OffsetDateTime::from_unix_timestamp(1350085394).unwrap()
        ),
        window: Some(Duration::HOUR),
        vendor: Vendor::Github
    },
);
