Struct StdError

pub struct StdError(pub Box<dyn Error + Send + Sync>);

An escape hatch to preserve stack traces when we don’t know the error.

This crate exports some traits such as Conn and Listener. The trait functions produce the local error util::Error. However when used in crates higher up the stack, we are forced to handle errors that are local to that crate. For example we use Listener the dtls crate and it needs to handle dtls::Error.

By using util::Error::from_std we can preserve the underlying error (and stack trace!).

Trait Implementations

impl Debug for StdError

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

Formats the value using the given formatter.

impl Display for StdError

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

Formats the value using the given formatter.

impl Error for StdError

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 PartialEq for StdError

fn eq(&self, _: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
