Struct Error 

pub struct Error { /* private fields */ }

A good general-purpose error type.

If debug_assertions and the alloc feature are enabled, then this error will have the same behavior as BoxedError. Otherwise, it will behave like Failure.

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.

impl Source for Error

fn new<T: Error + Send + Sync + 'static>(source: T) -> Self

Returns a new Self using the given Error.

impl Trace for Error

fn trace<R>(self, trace: R) -> Self

where R: Debug + Display + Send + Sync + 'static,

Adds an additional trace to this error, returning a new error.
