Enum HarnessError 

pub enum HarnessError {
    Spawn(Error),
    ExitStatus(ExitStatus),
    Timeout(Duration),
    NoResults,
    Protocol(String),
}

Errors from driving an adapter.

Variants

Spawn(Error)

The adapter binary could not be spawned at all.

ExitStatus(ExitStatus)

The adapter exited nonzero — harness error, not a check failure.

Timeout(Duration)

The adapter outlived its wall-clock budget and was killed.

NoResults

The adapter emitted zero parseable check results.

Protocol(String)

A protocol line was structurally invalid.

Trait Implementations

impl Debug for HarnessError

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

Formats the value using the given formatter.

impl Display for HarnessError

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

Formats the value using the given formatter.

impl Error for HarnessError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
