The reason a packet was dropped without being handled.

Variants

Packet(Error)

The packet could not be parsed.

UnsupportedEthertype(EthernetProtocol)

The ethertype is unknown.

UnsupportedIpProtocol(IpProtocol)

The ethertype is unknown.

UnsupportedIcmpv6(Icmpv6Message)

The ICMPv6 message type is unsupported.

UnsupportedDhcp(DhcpMessageType)

The ARP type is unsupported.

UnsupportedArp

The ARP type is unsupported.

Ipv4Checksum

The IPv4 checksum was invalid.

SendBufferFull

The send buffer is invalid.

Io(Error)

There was an IO error.

BadTcpState(TcpError)

The TCP state is invalid.

UnsupportedDhcpv6(MessageType)

The DHCPv6 message type is unsupported.

UnsupportedNdp(NdpMessageType)

The NDP message type is unsupported.

MalformedPacket

An incoming packet was recognized but was self-contradictory. E.g. a TCP packet with both SYN and FIN flags set.

IpLengthMismatch

The IP total-length field does not match the buffer size.

FragmentedPacket

An incoming IP packet has been split into several IP fragments and was dropped, since IP reassembly is not supported.

DestinationNotAllowed

The destination address is not allowed (e.g., loopback, unspecified, or link-local when host-local access is disabled).

Trait Implementations

impl Debug for DropReason

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

Formats the value using the given formatter.

impl Display for DropReason

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

Formats the value using the given formatter.

impl Error for DropReason

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 From<Error> for DropReason

fn from(source: Error) -> Self

Converts to this type from the input type.
