Enum ExecError 

pub enum ExecError {
    CommandFailed(i32),
    RunFailed(String),
    Cancelled,
    LookPathFailed(String),
}

Errors ported from the sentinel errors.New/fmt.Errorf values in exec.go.

Named ExecError (rather than Error, which Go’s error interface doesn’t require naming) to leave std::result::Result’s Err type unambiguous when this crate’s own ExecResult struct is also in scope.

Variants

CommandFailed(i32)

Ported from ErrCommandFailed.

RunFailed(String)

Ported from the fmt.Errorf("running command: %w", ...) wrap around a go-cmd/os/exec start failure (binary missing, permission denied, etc).

Cancelled

Ported from context cancellation overriding the result (ctx.Err() checked after the command finishes).

LookPathFailed(String)

Ported from LookPath’s wrapped exec.LookPath error.

Trait Implementations

impl Debug for ExecError

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

Formats the value using the given formatter.

impl Display for ExecError

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

Formats the value using the given formatter.

impl Error for ExecError

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.
