Enum EncodingVersion 

pub enum EncodingVersion {
    Xcdr1,
    Xcdr2,
}

CDR writer for serialization.

Handles alignment and endianness for ROS 2 CDR encoding. Alignment is computed relative to origin — when a 4-byte CDR header is present, origin = 4 so that fields align correctly within the payload portion of the buffer. CDR encoding version. XCDR1 is the historical default (PLAIN_CDR, no DHEADER, 8-byte primitives align to 8). XCDR2 (phase-303 W2 / RFC-0055 / #0267) is DELIMITED_CDR for APPENDABLE types: every struct is wrapped in a 4-byte DHEADER and 8-byte primitives align to 4.

Variants

Xcdr1

PLAIN_CDR (encapsulation 0x0001). The default; byte-identical to every pre-W2 stream.

Xcdr2

DELIMITED_CDR2 (encapsulation 0x0009) — appendable + DHEADER.

Trait Implementations

impl Clone for EncodingVersion

fn clone(&self) -> EncodingVersion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for EncodingVersion

impl Debug for EncodingVersion

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

Formats the value using the given formatter.

impl Default for EncodingVersion

fn default() -> EncodingVersion

Returns the “default value” for a type.

impl Eq for EncodingVersion

impl PartialEq for EncodingVersion

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