pub enum TestRunError {
    Spawn {
        package: String,
        target: String,
        executable: PathBuf,
        source: Error,

}

Errors produced while running tests.

target: String

executable: PathBuf

source: Error

Wait

The OS started the test executable, but waiting for it to finish failed.

Fields

package: String

target: String

executable: PathBuf

source: Error

OutputIo(Error)

Reading stdout / stderr from the child process failed.

SinkIo(Error)

Writing captured stdout / stderr to the sink failed. The runner stops at the first failure rather than continuing silently.

Trait Implementations

impl Debug for TestRunError

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

Formats the value using the given formatter.

impl Display for TestRunError

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

Formats the value using the given formatter.

impl Error for TestRunError

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)
