Enum Error 

pub enum Error {
    Message(String),
    NotImplemented,
    Probe {
        phase: &'static str,
        source: Box<Error>,
    },
    Iperf3Missing,
    Mqtt(String),
    Http(Error),
    Url(ParseError),
    Io(Error),
    Json(Error),
}

Failure from discovery, measurement, or export helpers.

Match on this instead of string-matching Display output:

• Error::Iperf3Missing — iperf3 binary not found when using Iperf3Engine
• Error::Probe — a named measurement phase failed (for example "download"); the source chain holds the underlying error
• Error::Http, Error::Io, Error::Json — transparent wrappers for reqwest, I/O, and JSON errors

Variants

Message(String)

General failure with a message (unknown server id, invalid CLI combination in the binary crate, etc.).

NotImplemented

Probe

A measurement phase failed; inspect phase and source.

Fields

phase: &'static str

source: Box<Error>

Iperf3Missing

Mqtt(String)

MQTT publish failure (CLI crate).

Http(Error)

Url(ParseError)

Io(Error)

Json(Error)

Implementations

impl Error

pub fn probe(phase: &'static str, source: impl Into<Error>) -> Self

pub fn from_reqwest(phase: &'static str, err: Error) -> Self

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
