Enum PopenError

#[non_exhaustive]
pub enum PopenError {
    IoError(Error),
    LogicError(&'static str),
}

Error in Popen calls.

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.

IoError(Error)

An IO system call failed while executing the requested operation.

LogicError(&'static str)

A logical error was made, e.g. invalid arguments detected at run-time.

Trait Implementations

impl Debug for PopenError

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

Formats the value using the given formatter.

impl Display for PopenError

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

Formats the value using the given formatter.

impl Error for PopenError

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<CommunicateError> for PopenError

fn from(err: CommunicateError) -> PopenError

Converts to this type from the input type.

impl From<Error> for PopenError

fn from(err: Error) -> PopenError

Converts to this type from the input type.
