Module extrapolate_rate 

Implementations of rate, increase and delta functions in PromQL.

Structs

CounterResetIndex 🔒

Positions of the counter resets in a value array, so that a window can accumulate the resets it contains instead of scanning all of its samples.

ExtrapolatedRate

Part of the extrapolatedRate in Promql, from https://github.com/prometheus/prometheus/blob/v0.40.1/promql/functions.go#L66

Functions

add_counter_resets 🔒

Adds the value preceding every counter reset in values to result, in sample order.

add_counter_resets_between_samples 🔒

Same additions add_counter_resets performs, over the samples in [first, last] instead of over every slot.

extract_eval_timestamps 🔒

valid_window_bounds 🔒

Locates the samples inside [offset, offset + length), returning the first and last non-null index together with the number of non-null slots. Returns None when the window holds no sample.
