Enum subprocess::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)

The underlying error is io::Error.

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

impl Error for PopenError

fn description(&self) -> &str

Deprecated since 1.41.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

impl From<CommunicateError> for PopenError

fn from(err: CommunicateError) -> PopenError

Performs the conversion.

impl From<Error> for PopenError

fn from(err: Error) -> PopenError

Performs the conversion.
