    NotFound(String),
    NotExecutable(String),
    Io(Error, Option<String>),
}

An error which may arise when spawning a command process.

Variants

NotFound(String)

Trait Implementations

impl Debug for CommandError

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

Formats the value using the given formatter.

impl Display for CommandError

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

Formats the value using the given formatter.

impl Error for CommandError

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 From<CommandError> for RuntimeError

fn from(source: CommandError) -> Self

Converts to this type from the input type.

impl IsFatalError for CommandError

fn is_fatal(&self) -> bool

Checks whether the error should be considered a “fatal” error.

impl PartialEq for CommandError

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
