This mostly looks reasonable. I'll make some changes on top of this before release to avoid the type breakage and the builder pattern breakage. Thanks for the contribution |

* fix: expose Builder::with_clock and add Default for StdClock Builder::with_clock was pub(crate), leaving no_std users without a way to build a Ratelimiter with custom max_tokens or initial_available — the only public no_std constructor was Ratelimiter::with_clock, which takes neither. Make it pub and document it. Also add impl Default for StdClock to satisfy clippy::new_without_default and pair the ergonomic new() constructor with a Default impl. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat: default Clock type parameter to StdClock Make the Clock generic default to StdClock when the std feature is enabled, so callers can name Ratelimiter and Builder without generics in type position — e.g. fn foo(rl: &Ratelimiter) stays valid. Because StdClock itself is gated by #[cfg(feature = "std")], the default can't be expressed unconditionally; the struct declarations for Ratelimiter and Builder are cfg-duplicated with and without the default. The impl blocks are unaffected. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Hello!
This PR seeks to make the crate
#[no_std]first withstdas the default feature. This is because most of the crate can use the things incorewith the exception ofInstant. This PR makesRatelimitergeneric overClockand providesStdClockfor users that want to usestd. I have made changes to the test as well to not rely onsleep
