Struct NetCounters 

pub struct NetCounters {
    pub rx_bytes: u64,
    pub tx_bytes: u64,
}

Host-wide network byte counters, cumulative since boot.

Loopback is excluded by both backends: lo traffic never reaches a wire, and counting it would both inflate the figure and double every byte (once as received, once as transmitted). A container or a busy local database would otherwise report hundreds of MB/s of “network” while the NIC is idle.

Fields

rx_bytes: u64

tx_bytes: u64

Implementations

impl NetCounters

pub fn delta(&self, prev: &NetCounters) -> NetCounters

Counter delta against an earlier sample, saturating on reset.

A counter can go backwards: an interface is destroyed and recreated, or the kernel wraps the counter on 32-bit if_data. Reporting a negative rate (or a 4 GiB spike) for one tick is worse than reporting zero, so a decreasing counter contributes nothing.

pub fn per_sec(&self, prev: &NetCounters, secs: f64) -> Rate

Bytes per second between two samples secs apart.
