Class: Async::Limiter::Timing::FixedWindow

Inherits:
SlidingWindow show all
Defined in:
lib/async/limiter/timing/fixed_window.rb

Overview

Fixed window timing strategy with discrete boundaries aligned to clock time.

Fixed windows reset at specific intervals (e.g., every minute at :00 seconds), creating predictable timing patterns and allowing bursting at window boundaries.
