Implementations§

impl StatsSnapshot

pub const fn total_packets(&self) -> u64

Returns the total packets (TX + RX).

pub const fn total_bytes(&self) -> u64

Returns the total bytes (TX + RX).

pub fn nat_hit_rate(&self) -> f64

Returns the NAT fast path hit rate (0.0 - 1.0).

pub fn poll_efficiency(&self) -> f64

Returns the poll efficiency (ratio of iterations with work).

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

Computes the delta between two snapshots.
