The type returned when attaching an UProbe fails.

Fields

symbol: String

symbol name.

error: Box<dyn Error + Send + Sync>

the original error.

FileError

There was an error accessing filename.

Fields

filename: PathBuf

The file name

io_error: Error

Trait Implementations

impl Debug for UProbeError

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

Formats the value using the given formatter.

impl Display for UProbeError

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

Formats the value using the given formatter.

impl Error for UProbeError

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.

impl From<UProbeError> for ProgramError

fn from(source: UProbeError) -> Self

Converts to this type from the input type.
