Struct DdsAny 

pub struct DdsAny {
    pub type_name: String,
    pub payload: Vec<u8>,
}

IDL-any als Type-Erasure-Wrapper. Traegt einen Type-Identifier- String (z.B. "std_msgs::Header") plus die Payload-Bytes.

Konsumenten-Pattern: man prueft type_name, deserialisiert die payload mit dem konkreten DdsType.

Fields

type_name: String

Voll-qualifizierter Type-Name (entspricht DdsType::TYPE_NAME).

payload: Vec<u8>

XCDR2-Payload-Bytes des wraped Werts.

Implementations

impl DdsAny

pub fn pack<T: DdsType>(value: &T) -> Result<Self, EncodeError>

Konstruiert ein DdsAny aus einem DdsType-Wert.

Errors

EncodeError bei Encode-Fehler.

pub fn unpack<T: DdsType>(&self) -> Result<T, DecodeError>

Versucht das Wrapped als T zu entpacken.

Errors

DecodeError::Invalid wenn T::TYPE_NAME != self.type_name oder Decode-Fehler.

Trait Implementations

impl CdrDecode for DdsAny

fn decode(r: &mut BufferReader<'_>) -> Result<Self, DecodeError>

Liest diesen Wert aus dem Reader (alignment-bewusst).

impl CdrEncode for DdsAny

fn encode(&self, w: &mut BufferWriter) -> Result<(), EncodeError>

Schreibt diesen Wert in den Writer (alignment-bewusst).

impl Clone for DdsAny

fn clone(&self) -> DdsAny

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DdsAny

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

Formats the value using the given formatter.

impl Default for DdsAny

fn default() -> DdsAny

Returns the “default value” for a type.

impl PartialEq for DdsAny

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