Enum CmdError 

pub enum CmdError {
    CmdFailure {
        cmd: Cmd,
        stderr: String,
        stdout: String,
        status: ExitStatus,
    },
    Io {
        cmd: Cmd,
        source: Error,
    },
    Utf8 {
        cmd: Cmd,
        source: Utf8Error,
    },
    FromUtf8 {
        cmd: Cmd,
        source: FromUtf8Error,
    },
}

Command execution errors with contextual details.

Each variant embeds Cmd (program, args, cwd) for terse diagnostics. Utf8 is currently not produced by CmdExt::exec but kept for potential future APIs.

Trait Implementations

impl Debug for CmdError

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

Formats the value using the given formatter.

impl Display for CmdError

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

Formats the value using the given formatter.

impl Error for CmdError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn provide<'_request>(&'_request self, request: &mut Request<'_request>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

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
