Errors surfaced to the user.

Variants

ConnectionRefused

The connection was refused, RST segment received while in SYN_SENT state.

ConnectionReset

The connection was reset because of a RST segment.

NetworkUnreachable

The connection was closed because the network is unreachable.

HostUnreachable

The connection was closed because the host is unreachable.

ProtocolUnreachable

The connection was closed because the protocol is unreachable.

PortUnreachable

The connection was closed because the port is unreachable.

DestinationHostDown

The connection was closed because the host is down.

SourceRouteFailed

The connection was closed because the source route failed.

SourceHostIsolated

The connection was closed because the source host is isolated.

TimedOut

The connection was closed because of a time out.

PermissionDenied

The connection was closed because of a lack of required permissions.

ProtocolError

The connection was closed because there was a protocol error.

Trait Implementations

impl Clone for ConnectionError

fn clone(&self) -> ConnectionError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectionError

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

Formats the value using the given formatter.

impl Display for ConnectionError

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

Formats the value using the given formatter.

impl Error for ConnectionError

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 ConnectionError

fn eq(&self, other: &ConnectionError) -> 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.
