Pace

1 VersionUtility

Regulates a fixed leg a and a variadic pack of independently typed legs to one output rate in Hz, driven by Pace's own monotonic timer. A zero-order-hold resampler: drops inputs faster than rate, duplicates the last value when idle, never interpolates.

How it fits

Typical backends

A bursty detection stream is regulated to a steady 10 Hz before a sink that needs a fixed cadence; faster bursts are decimated and an idle stretch is filled by duplicating the last value so the downstream rate never stalls.

Two independently typed legs that update at different rates are co-regulated onto one shared cadence so a consumer always sees both legs' newest values together on every tick, the slower leg zero-order-held between its updates.

Caveats

I/O contractThe leg count and per-leg types of the output match the input exactly; a value is never transformed, only dropped or duplicated, so a consumer sees the same a (and each pack type) it would without the regulator.
Hard constraintNothing is emitted until every leg has carried at least one value; a leg with no value yet cannot be zero-order-held and a partial tuple would desync the output legs, so a permanently silent input stalls all output.
Parameter interactionUnder the regulate mode an idle leg's last value is duplicated every tick (heartbeat) so output continues with no input; under the drop_only mode no value is ever duplicated and output stops entirely while the inputs are idle.
FallbackSurplus arrivals faster than rate are dropped, not buffered; only the newest value of each leg survives to the next emit, so intermediate values between two ticks are lost.
