Enum ProcessError 

#[non_exhaustive]
pub enum ProcessError {
    Missing {
        program: String,
    },
    Refused {
        program: String,
        arg: String,

Why a process couldn’t run to its end.

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.

Missing

The program isn’t on PATH.

Fields

program: String

The program.

Refused

An argument a Windows cmd /C wrapper would read as an operator.

Fields

program: String

The program.

arg: String

The argument, escaped.

Elevation

It needed elevation (Hyper-V’s), which couldn’t be had: the prompt declined, the elevated session ended.

Fields

reason: String

Why.

Io

Starting it, piping it or waiting for it failed.

Fields

program: String

The program.

source: Error

The OS’s reason.

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, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for ProcessError

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.
