Struct DataRepresentation 

pub struct DataRepresentation {
    pub value: Vec<i16>,
}

DDS-XTypes v1.3 Section 7.6.3.1 DATA_REPRESENTATION QoS policy.

A DataWriter offers a single data representation (the first element of the list, or XCDR1 if the list is empty). A DataReader requests one or more accepted representations. The policies are compatible when the writer’s offered representation is contained in the reader’s requested list.

On the wire this is PID_DATA_REPRESENTATION (0x0073), a CDR sequence<int16>.

Fields

value: Vec<i16>

Implementations

impl DataRepresentation

pub fn offered_representation(maybe: Option<&DataRepresentation>) -> i16

The single representation a DataWriter with this (optional) policy uses: the first list element, or XCDR1 when absent/empty (DDS-XTypes 7.6.3.1.1).

pub fn accepted_representations(maybe: Option<&DataRepresentation>) -> Vec<i16>

The representations a DataReader with this (optional) policy accepts: the list, or [XCDR1] when absent/empty (DDS-XTypes 7.6.3.1.1).

Trait Implementations

impl Clone for DataRepresentation

fn clone(&self) -> DataRepresentation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataRepresentation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DataRepresentation

fn deserialize<__D>( __deserializer: __D, ) -> Result<DataRepresentation, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for DataRepresentation

impl Hash for DataRepresentation

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for DataRepresentation

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