Struct FixedWindowCounter 

pub struct FixedWindowCounter<P: Precision, T: TimeSource> { /* private fields */ }

Fixed window counter rate limiter with integrated time source and precision handling.

The fixed window counter algorithm divides time into fixed-size windows and tracks the number of requests within each window. When a window expires, the counter resets to zero, allowing new requests up to the capacity limit.

Type Parameters

• P - The precision type that determines how Duration values are converted to internal ticks
• T - The time source type that provides elapsed time since the rate limiter’s reference point
