Struct GUID

pub struct GUID {
    pub prefix: GuidPrefix,
    pub entity_id: EntityId,
}

DDS/RTPS GUID

Spec 2.5, Section 8.2.4.1 Identifying RTPS entities: the GUID

The GUID (Globally Unique Identifier) is an attribute of all RTPS Entities and uniquely identifies the Entity within a DDS Domain.

The GUID is built as a tuple <prefix, entityId> combining a GuidPrefix_t prefix and an EntityId_t entityId … The implementation is free to choose the prefix, as long as every Participant in the Domain has a unique GUID. … The GUIDs of all the Endpoints within a Participant have the same prefix.

Fields

prefix: GuidPrefix

entity_id: EntityId

Implementations

fn clone(&self) -> GUID

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GUID

impl Key for GUID

fn hash_key(&self, force_md5: bool) -> KeyHash

impl Ord for GUID

fn cmp(&self, other: &GUID) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for GUID

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

fn partial_cmp(&self, other: &GUID) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
