Available on crate features std and udp only.

Error from a packet-oriented datagram operation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Io(Error)

Operating-system or runtime I/O error.

SegmentationRejected(Error)

A validated segmented send was rejected by the socket’s offload implementation.

No segment was accepted. Query capabilities before retrying as ordinary datagrams. The original socket error is retained; other I/O failures are not classified this way.

Unsupported(DatagramFeature)

A requested feature is not available on this socket.

PayloadTooLarge

An unsegmented payload exceeds the implementation ceiling.

Fields

len: usize

Submitted payload length.

max: usize

Maximum accepted length.

InvalidSegmentSize

Segment metadata does not describe the submitted payload.

Fields

payload_len: usize

Submitted payload length.

segment_size: usize

Submitted segment size.

TooManySegments

A segmented datagram entry contains more segments than supported.

Fields

count: usize

Submitted segment count.

max: usize

Maximum accepted segment count.

SourceAddressFamilyMismatch

The selected source IP and destination use different address families.

Fields

source: IpAddr

Selected source IP.

destination: SocketAddress

Submitted destination.

ReceiveSlotMismatch

Receive buffers and metadata slots have different lengths.

Fields

buffers: usize

Number of receive buffers.

metadata: usize

Number of metadata slots.

EmptyReceiveBatch

A receive operation was submitted without any buffers.

Closed

The deterministic in-memory peer has shut down.

Implementations

impl DatagramError

pub fn send_failure(&self) -> SendFailure

Classify this error for a sender’s failure policy.

Trait Implementations

impl Debug for DatagramError

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

Formats the value using the given formatter.

impl Display for DatagramError

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

Formats the value using the given formatter.

impl Error for DatagramError

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 DatagramError

fn from(value: Error) -> DatagramError

Converts to this type from the input type.
