Enum ProcessError 

pub enum ProcessError {
    CommandParseFailure(String),
    SignalParseFailure(String),
    StartFailure(String),
    StopFailure(String),
    KillFailed(Errno),
    MutexPoisoned,
}

Custom error describing the error cases for the ProcessAction.

Variants

CommandParseFailure(String)

The command is invalid (usually mismatched quotations etc.).

SignalParseFailure(String)

Signal is not a valid UNIX signal.

StartFailure(String)

The underlying Rust command creation failed. The parameter contains the error.

StopFailure(String)

Stopping the command failed.

KillFailed(Errno)

Killing the command failed.

MutexPoisoned

The lock on the child is poisoned: this means the thread failed while holding the lock.

Trait Implementations

impl Debug for ProcessError

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

Formats the value using the given formatter.

impl Display for ProcessError

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

Formats the value using the given formatter.

impl Error for ProcessError

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 ProcessError

fn from(source: Errno) -> Self

Converts to this type from the input type.

impl From<ProcessError> for ActionError

fn from(value: ProcessError) -> Self

Converts to this type from the input type.

impl PartialEq for ProcessError

fn eq(&self, other: &ProcessError) -> 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.
