Struct StdError 

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

An escape hatch to preserve stack traces for errors whose concrete type is unknown.

Some traits exported by this crate (e.g. Conn, Listener) return Error. When those traits are used in higher-level crates that have their own error types, callers are forced to handle foreign errors. StdError boxes any std::error::Error implementation and wraps it in Error::Std, preserving the original error’s message and — where supported — its stack trace.

Use Error::from_std to construct this variant.

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.
