Implementations

impl Error

pub fn wrap(err: impl Error + Send + Sync + 'static) -> Self

pub fn msg(err: impl Error) -> Self

pub fn debug(err: impl Debug) -> Self

pub fn bt(self) -> Self

pub fn with_path<P: AsRef<Path>>(self, p: P) -> Self

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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
