Enum ExecutorError 

pub enum ExecutorError {
    UnsupportedOption(&'static str),
    MissingProgram(OsString),
    SpawnFailure(Error),
    Failure(SysexitsError, Option<String>),
    UnexpectedFailure(Option<i32>, Option<String>),
    UnexpectedOther(Error),
    IncompleteInput,
}

Available on crate feature std only.

A configuration failure, or a failure to launch, communicate with, or complete a child process.

Conversion from a process output decodes stderr strictly as UTF-8: invalid UTF-8 yields None, while empty stderr yields Some(String::new()). Conversion from an exit status alone has no stderr and always uses None.

Variants

UnsupportedOption(&'static str)

Supplied capability metadata declares a requested option unsupported. Contains the long option name (such as --sort); no child was spawned.

MissingProgram(OsString)

Spawning returned NotFound; contains the selected program name or path.

SpawnFailure(Error)

The process could not be started for a reason other than NotFound.

Failure(SysexitsError, Option<String>)

A recognized sysexits error and optional captured UTF-8 stderr.

UnexpectedFailure(Option<i32>, Option<String>)

An unrecognized exit code and optional captured UTF-8 stderr.

The code is None when termination has no numeric exit code, such as termination by a signal on Unix.

UnexpectedOther(Error)

An I/O failure outside spawning, such as copying stdin, waiting for the child, or decoding a prompter’s stdout as UTF-8.

IncompleteInput

The child exited successfully before its input feed completed. Use crate::ExecutionCompletion to explicitly handle intentional early exit.

Trait Implementations

impl Debug for ExecutorError

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

Formats the value using the given formatter.

impl Display for ExecutorError

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

Formats the value using the given formatter.

impl Error for ExecutorError

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
