Enum ProcessError 

pub enum ProcessError {
    NonAbsoluteCwd {
        cwd: PathBuf,
    },
    SpawnFailed {
        program: OsString,
        source: Error,
    },

    },

    },
}

Failure modes shared by every ProcessSpawner and Process method.

Variants

NonAbsoluteCwd

The cwd in the SpawnPlan was relative; absolute paths are required.

Fields

cwd: PathBuf

Relative cwd that was rejected.

SpawnFailed

The OS refused to spawn the child (executable not found, permission denied, fork/exec failure, etc.).

Fields

program: OsString

Program the executor tried to launch.

source: Error

Underlying I/O error.

SignalFailed

The OS refused to deliver a signal to the child, or the implementation does not support the requested signal on the host platform (e.g. SIGTERM / SIGINT on Windows).

Fields

signal: Signal

Signal the executor tried to deliver.

pid: Option<ProcessId>

Process id of the target, when available.

source: Error

Underlying I/O error.

WaitFailed

Reaping the child failed.

Fields

pid: Option<ProcessId>

Process id of the target, when available.

source: Error

Underlying I/O error.

Trait Implementations

impl Debug for ProcessError

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

Formats the value using the given formatter.

impl Display for ProcessError

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

Formats the value using the given formatter.

impl Error for ProcessError

where Self: Debug + Display,

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 ErrorCompat for ProcessError

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

Returns a Backtrace that may be printed.

fn iter_chain(&self) -> ChainCompat<'_, '_>

where Self: AsErrorSource,

Returns an iterator for traversing the chain of errors, starting with the current error and continuing with recursive calls to Error::source.
