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.

WriteOverflow

Ausgabe-Buffer zu klein.

Fields

needed: usize

Wieviele Bytes gebraucht worden waeren.

available: usize

Wieviele tatsaechlich verfuegbar waren.

UnexpectedEof

Eingabe endete vor dem erwarteten Ende.

Fields

needed: usize

Wieviele Bytes noch erwartet wurden.

offset: usize

Position im Stream zum Zeitpunkt des Fehlers.

UnknownSubmessageId

Submessage-ID ist nicht in 0..=15 (Spec §8.3.5).

Fields

id: u8

Roher Submessage-ID-Byte.

TruncatedSubmessageBody

SubmessageHeader-Length deutet auf Body, der ueber das Datagram- Ende hinaus reichen wuerde (Truncation).

Fields

declared: u16

Header-Wert submessage_length.

available: usize

Tatsaechlich verfuegbare Bytes ab Body-Start.

TooManySubmessages

Anzahl Submessages in einer Message ueberschreitet DOSC_MAX_SUBMESSAGES — DoS-Schutz.

Fields

limit: usize

Festes Limit.

PayloadTooLarge

Payload-Groesse ueberschreitet DOSC_MAX_PAYLOAD_SIZE — DoS-Schutz.

Fields

limit: usize

Limit.

actual: usize

Tatsaechliche Groesse.

UnalignedSubmessage

SubmessageLength ist nicht zum 4-Byte-Alignment passend (§8.3.3: Offset jeder Submessage muss multiple von 4 sein).

Fields

offset: usize

Offset, an dem das Problem auftrat.

ValueOutOfRange

Numerischer Wert ueberschreitet das Wire-Feld.

Fields

message: &'static str

Beschreibung.

Trait Implementations

impl Clone for XrceError

fn clone(&self) -> XrceError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XrceError

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

Formats the value using the given formatter.

impl Display for XrceError

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

Formats the value using the given formatter.

impl Error for XrceError

Available on crate feature std only.

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<XrceError> for XrceXmlError

fn from(e: XrceError) -> Self

Converts to this type from the input type.

impl PartialEq for XrceError

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