Struct Empty 

pub struct Empty {}

Empty message type

Trait Implementations

impl Clone for Empty

fn clone(&self) -> Empty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Empty

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

Formats the value using the given formatter.

impl Default for Empty

fn default() -> Empty

Returns the “default value” for a type.

impl Deserialize for Empty

fn deserialize(reader: &mut CdrReader<'_>) -> Result<Self, DeserError>

Deserialize a value from the CDR reader

impl Message for Empty

const TYPE_NAME: &'static str = "std_msgs/msg/Empty"

ROS topic-type name in package/msg/Type form (e.g. "std_msgs/msg/String").

const FIELDS: &'static [Field]

Field schema in declaration order.

const MAX_SERIALIZED_SIZE_XCDR1: Option<usize> = _

Phase 380 — the largest this type can serialize to, per encoding, or None when it is unbounded.

const MAX_SERIALIZED_SIZE_XCDR2: Option<usize> = _

See Self::MAX_SERIALIZED_SIZE_XCDR1.

const IS_PLAIN: bool = _

No variable-length member anywhere: the size above is EXACT and the type is loan-eligible (phase-380 W5).

impl PartialEq for Empty

fn eq(&self, other: &Empty) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl RosMessage for Empty

const TYPE_NAME: &'static str = "std_msgs::msg::dds_::Empty_"

Full ROS type name in DDS format

const TYPE_HASH: &'static str = "TypeHashNotSupported"

RIHS (ROS Interface Hashing Standard) type hash

const MAX_SERIALIZED_BOUND: Option<usize>

Issue 1179 / phase-498 W3 – the largest serialized size of this type, over XCDR1 and XCDR2, or None when no bound exists (an unbounded member) or nobody stated one.

const SERIALIZATION_FORMAT_ID: SerializationFormatId = nros_serdes::format::SerializationFormatId::Cdr

RFC-0088 — the serialization format this message’s bytes are in.

const STAMP_OFFSET: Option<usize> = None

RFC-0052 / phase-296 W3a — byte offset of header.stamp.sec within this type’s serialized CDR payload (encapsulation header included), or None when the type has no leading std_msgs/Header / builtin_interfaces/Time. Codegen-const, never runtime introspection: CDR here is little-endian with a 4-byte encapsulation header and Time { i32 sec; u32 nanosec } is 4-byte aligned, so a Header-leading (or Time-leading) type carries sec at byte 4 and nanosec at byte 8. On-target max_age monitors peek these two words from the raw receive buffer before deserialization.

impl Serialize for Empty

fn serialize(&self, writer: &mut CdrWriter<'_>) -> Result<(), SerError>

Serialize this value to the CDR writer
