CDR Representation Identifier (2 bytes)

Per RTPS v2.5 Section 10.5, Table 10.3 and DDS X-Types 1.3 Section 7.6.2.1.2

The representation identifier specifies the encoding format and byte order used for the serialized data payload.

Supported Encodings

Only plain CDR v1 is supported by this implementation:

• CdrLE - CDR Little Endian (recommended, default)
• CdrBE - CDR Big Endian

All other encodings (Parameter List, XCDR v2) will fail during serialization/deserialization.

Variants

CdrBE = 0

CDR Big Endian (v1) - [0x00, 0x00] ✓ Supported

CdrLE = 1

CDR Little Endian (v1) - [0x00, 0x01] ✓ Supported

PlCdrBE = 2

Parameter List CDR Big Endian - [0x00, 0x02] ✗ Not supported

PlCdrLE = 3

Parameter List CDR Little Endian - [0x00, 0x03] ✗ Not supported

Xcdr2BE = 6

XCDR v2 Big Endian (X-Types 1.3) - [0x00, 0x06] ✗ Not supported

Xcdr2LE = 7

XCDR v2 Little Endian (X-Types 1.3) - [0x00, 0x07] ✗ Not supported

DCdr2BE = 8

Delimited CDR v2 Big Endian - [0x00, 0x08] ✗ Not supported

DCdr2LE = 9

Delimited CDR v2 Little Endian - [0x00, 0x09] ✗ Not supported

PlXcdr2BE = 10

Parameter List XCDR v2 Big Endian - [0x00, 0x0a] ✗ Not supported

PlXcdr2LE = 11

Parameter List XCDR v2 Little Endian - [0x00, 0x0b] ✗ Not supported

Implementations

impl RepresentationIdentifier

pub const fn is_little_endian(&self) -> bool

Returns true if this representation uses little-endian byte order

pub const fn is_big_endian(&self) -> bool

Returns true if this representation uses big-endian byte order

pub const fn is_plain_cdr(&self) -> bool

Returns true if this is a plain CDR v1 encoding (CdrBE or CdrLE)

Only plain CDR v1 encodings are supported by this implementation.

pub const fn is_supported(&self) -> bool

Returns true if this encoding is supported by the current implementation

Currently only plain CDR v1 (CdrBE, CdrLE) is supported. Parameter List and XCDR v2 encodings are not supported.

pub const fn is_cdr_v1(&self) -> bool

Returns true if this is a CDR v1 encoding (including Parameter List CDR)

pub const fn is_cdr_v2(&self) -> bool

Returns true if this is a CDR v2 / XCDR2 encoding

pub const fn is_parameter_list(&self) -> bool

Returns true if this is a Parameter List encoding

pub const fn to_bytes(&self) -> [u8; 2]

Convert to raw bytes (big-endian as per spec)

pub fn from_bytes(bytes: [u8; 2]) -> Result<Self>

Parse from raw bytes

Trait Implementations

impl Clone for RepresentationIdentifier

fn clone(&self) -> RepresentationIdentifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RepresentationIdentifier

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

Formats the value using the given formatter.

impl Default for RepresentationIdentifier

fn default() -> Self

Default to CDR Little Endian (most common for x86/ARM)

impl PartialEq for RepresentationIdentifier

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