Struct Error 

pub struct Error { /* private fields */ }

An error that can possibly inherit from a parent error.

Errors can be enriched with additional information, such as the raw output of a command or a human-friendly explanation.

pub fn with_output(self, output: impl Into<String>) -> Self

pub fn description(&self) -> &str

pub fn source(&self) -> Option<&Error>

pub fn explanation(&self) -> Option<&str>

pub fn output(&self) -> Option<&str>

pub fn with_context(self, description: impl Into<String>) -> 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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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.
