Enum Error 

pub enum Error {
    ProcessId(ParseIntError),
    JobId(FindError),
    Unowned,
    Unmonitored,
    Finished,
    System(Errno),
}

Error that may occur while sending a signal.

Variants

ProcessId(ParseIntError)

The specified process (group) ID was not a valid integer.

JobId(FindError)

The specified job ID did not uniquely identify a job.

Unowned

The target job is not controlled by the current shell environment.

Unmonitored

The job ID specifies a job that is not job-controlled.

Finished

The target job has finished.

System(Errno)

An error occurred in the underlying system call.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

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<Errno> for Error

fn from(source: Errno) -> Self

Converts to this type from the input type.

impl From<FindError> for Error

fn from(source: FindError) -> Self

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(source: ParseIntError) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
