pub fn with_context(self, key: &'static str, value: impl ToString) -> Self

Add one more context in error.

pub fn with_source(self, src: impl Into<Error>) -> Self

Set source for error.

Panics

If the source has been set, we will raise a panic here.

pub fn sources(&self) -> impl ExactSizeIterator<Item = &(dyn Error + 'static)>

Return an iterator over all sources of this error.

pub fn from_io_error(err: Error) -> Error

Default constructor for Error from io::Error.

pub fn from_fmt_error(err: Error) -> Error

Default constructor for Error from fmt::Error.

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.
