Network error codes.

These errors cover all network stack operations from Ethernet to UDP.

Variants

PacketTooShort = 1

The packet is too short to contain the expected header.

PacketTooLarge = 2

The packet exceeds the maximum allowed size.

InvalidEthernetFrame = 3

Invalid Ethernet frame format.

UnsupportedEtherType = 4

Unknown or unsupported EtherType.

InvalidIpv4Header = 5

Invalid IPv4 header format or checksum.

Ipv4ChecksumError = 6

IPv4 header checksum mismatch.

InvalidIpVersion = 7

IPv4 version is not 4.

InvalidIpHeaderLength = 8

IPv4 header length is invalid.

TtlExpired = 9

IPv4 Time To Live expired.

InvalidUdpHeader = 10

Invalid UDP header format or checksum.

UdpChecksumError = 11

UDP checksum mismatch.

InvalidIcmpHeader = 12

ArpNotFound = 14

No ARP entry found for the target IP.

ArpCacheFull = 15

ARP cache is full.

SocketNotBound = 16

The socket is not bound to a port.

PortInUse = 17

The port is already in use.

NoPortsAvailable = 18

No available ports for ephemeral allocation.

DestinationUnreachable = 19

The destination is unreachable.

DeviceError = 20

Network device error.

BufferTooSmall = 21

FragmentationNotSupported = 24

Fragment reassembly not supported.

KernelError(u16)

Kernel error passthrough.

Implementations

impl NetError

pub const fn as_str(&self) -> &'static str

Returns a human-readable description of the error.

pub const fn code(&self) -> u16

Returns the error code as a u16 (for unit variants).

pub const fn from_u16(code: u16) -> Option<Self>

Converts from a raw u16 error code.

Trait Implementations

impl Clone for NetError

fn clone(&self) -> NetError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetError

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

Formats the value using the given formatter.

impl From<KernelError> for NetError

fn from(err: KernelError) -> Self

Converts to this type from the input type.

impl Hash for NetError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for NetError

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