Struct EventRate 

pub struct EventRate {
    pub starts: Vec<i64>,
    pub counts: Vec<u64>,
    pub positive: Vec<u64>,
    pub negative: Vec<u64>,
    pub bin_us: i64,
}

Activity over time, binned into fixed-width intervals.

starts holds each bin’s left edge in the stream’s own timestamp units, so it lines up with EventStream::ts() without conversion. The three count arrays are the same length as starts.

Fields

starts: Vec<i64>

Left edge of each bin, in stream timestamp units (µs).

counts: Vec<u64>

Events of either polarity in each bin.

positive: Vec<u64>

Positive-polarity events in each bin.

negative: Vec<u64>

Negative-polarity events in each bin.

bin_us: i64

Bin width in stream timestamp units (µs).

Implementations

impl EventRate

pub fn per_second(&self) -> Vec<f64>

Events per second in each bin — counts divided by the bin width.

Separate from counts because the bins are uniform: dividing is only meaningful if every bin covers the same span, which is exactly what this binning guarantees and what a caller aggregating by some other rule could not assume.

pub fn len(&self) -> usize

Number of bins.

pub fn is_empty(&self) -> bool

True when the stream was empty and there is nothing to plot.
