Struct Iperf3Engine 

pub struct Iperf3Engine { /* private fields */ }

iperf3 measurement by spawning the system iperf3 binary with -J JSON output.

Requires iperf3 on PATH unless overridden with with_binary. UDP mode (with_udp) fills jitter and packet loss; TCP mode does not.

Implementations

impl Iperf3Engine

pub fn new() -> Self

Default engine: iperf3 on PATH, 5 s per direction, TCP.

pub fn with_binary(self, binary: impl Into<PathBuf>) -> Self

Path to the iperf3 executable (default: "iperf3" on PATH).

pub fn with_duration_secs(self, secs: u64) -> Self

Test duration in seconds for each iperf3 direction (minimum 1).

pub fn with_udp(self, udp: bool) -> Self

Use UDP (-u) instead of TCP; enables packet-loss reporting when the server supports it.

pub fn with_bandwidth(self, bandwidth: impl Into<String>) -> Self

UDP target bandwidth passed to iperf3 -b (default "10M").

pub fn bps_from_json(json: &Iperf3Json, reverse: bool) -> Result<f64, Error>

Parse bps from fixture/live JSON. reverse → prefer received (download).

pub fn udp_stats(json: &Iperf3Json) -> (Option<f64>, Option<f64>)
