Implementations

impl MarsError

pub fn exit_code(&self) -> i32

Map error variants to CLI exit codes.

• 1: sync completed with unresolved conflicts
• 2: resolution/validation/config error
• 3: source, I/O, HTTP, or git CLI error

Trait Implementations

impl Debug for MarsError

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

Formats the value using the given formatter.

impl Display for MarsError

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

Formats the value using the given formatter.

impl Error for MarsError

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
