Struct subprocess::CommunicateError

pub struct CommunicateError {
    pub error: Error,
    pub capture: (Option<Vec<u8>>, Option<Vec<u8>>),
}

Error during communication.

It holds the underlying io::Error in the error field, and also provides the data captured before the error was encountered in the capture field.

The error description and cause are taken from the underlying IO error.

Fields

error: Error

The underlying io::Error.

capture: (Option<Vec<u8>>, Option<Vec<u8>>)

The data captured before the error was encountered.

Methods

impl CommunicateError

pub fn kind(&self) -> ErrorKind

Returns the corresponding IO ErrorKind for this error.

Equivalent to self.error.kind().

Trait Implementations

impl Error for CommunicateError

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.
