Enum ProcResult

#[non_exhaustive]
pub enum ProcResult {
    Unix(WaitStatus),
    Windows(ExitCode),
}

An exit code or exit state returned by a program.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unix(WaitStatus)

An unclassified exit status on a Unix platform.

Windows(ExitCode)

An unclassified exit status on a Windows platform.

Implementations

impl ProcResult

pub fn ok(&self) -> Result<(), Self>

Returns a result that is Ok if the exit code or status indicates a success.

Errors

Returns Self if not ProcResult::is_success.

pub fn is_success(&self) -> bool

Returns whether the process terminated successfully.

pub fn is_failure(&self) -> bool

Returns whether the process did not terminate successfully.

Trait Implementations

impl Clone for ProcResult

fn clone(&self) -> ProcResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProcResult

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

Formats the value using the given formatter.

impl Display for ProcResult

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

Formats the value using the given formatter.

impl Error for ProcResult

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<ExitStatus> for ProcResult

fn from(status: ExitStatus) -> Self

Converts to this type from the input type.

impl PartialEq for ProcResult

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