Fehler beim Decoden eines Werts.

Variants

UnexpectedEof

Eingabe endete vor dem erwarteten Ende.

Fields

needed: usize

Wieviele Bytes noch erwartet wurden.

offset: usize

Position im Stream, wo das EOF auftrat.

InvalidUtf8

UTF-8-Validierung fuer einen String-Wert ist fehlgeschlagen.

Fields

offset: usize

Position, an der der String begann.

InvalidBool

Boolean-Byte war weder 0 noch 1 — XCDR-Spec verbietet das.

Fields

value: u8

Tatsaechlich gelesenes Byte.

offset: usize

Position des Bytes.

InvalidChar

Char-Wert ist kein gueltiger Unicode-Codepoint.

Fields

value: u32

Tatsaechlich gelesener u32-Wert.

offset: usize

Position.

LengthExceeded

Sequence-/Array-Laenge ueberschreitet Bound oder die noch vorhandenen Bytes.

Fields

announced: usize

Wieviele Elemente die Laenge ankuendigt.

remaining: usize

Wieviele tatsaechlich noch lesbar sind (best-effort).

offset: usize

Position.

InvalidString

String-Format-Verletzung (z.B. Null-Terminator fehlt, Laenge 0).

Fields

offset: usize

Position, an der der String begann.

reason: &'static str

Kurzbeschreibung (statisch).

InvalidEnum

Unbekannter/ungueltiger Enum-Discriminator — wird von Policy- Decodern genutzt, die strict-mode operieren (z.B. QoS-Enums).

Fields

kind: &'static str

Enum-Name fuer Debugging (z.B. “DurabilityKind”).

value: u32

Gelesener Discriminator-Wert.

UnknownMustUnderstandMember

Mutable-Decode hat einen must_understand-Member mit unbekannter Member-ID gelesen (XTypes 1.3 §7.4.1.2.3 — Receiver MUSS in dem Fall die Message verwerfen).

Fields

member_id: u32

Member-ID die nicht erkannt wurde.

MissingNonOptionalMember

Mutable-Decode hat einen non-optional Member nicht im Wire gefunden (XTypes 1.3 §7.4.1.2.3).

Fields

member_id: u32

Member-ID die fehlt.

Trait Implementations

impl Clone for DecodeError

fn clone(&self) -> DecodeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeError

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

Formats the value using the given formatter.

impl Display for DecodeError

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

Formats the value using the given formatter.

impl Error for DecodeError

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 PartialEq for DecodeError

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