Struct InterGroupDelay 

pub struct InterGroupDelay {
    pub delta_ms: f64,
    pub at: Instant,
    pub size: usize,
}

The delay gradient between two consecutive groups.

This is the measurement everything downstream is built on: if the path is not queueing, packets spread apart on arrival exactly as much as they were spread apart on departure, and this is zero. A growing queue makes arrivals spread more than departures, and it goes positive.

Fields

delta_ms: f64

Arrival spread minus departure spread, in milliseconds. Positive means the queue is growing.

at: Instant

When the later group’s last packet departed — the instant this measurement belongs to.

size: usize

Bytes in the later group, for the rate calculation downstream.
