Implementations

impl HeaderFixedSize

pub fn create_topic_with_name( participant: &DdsParticipant, name: &str, maybe_qos: Option<DdsQos>, maybe_listener: Option<DdsListener>, ) -> Result<DdsTopic<Self>, DDSError>

Create a topic using of this Type specifying the topic name

Arguments

• participant - The participant handle onto which this topic should be created
• name - The name of the topic
• maybe_qos - A QoS structure for this topic. The Qos is optional
• maybe_listener - A listener to use on this topic. The listener is optional

pub fn create_topic( participant: &DdsParticipant, maybe_topic_prefix: Option<&str>, maybe_qos: Option<DdsQos>, maybe_listener: Option<DdsListener>, ) -> Result<DdsTopic<Self>, DDSError>

Create a topic of this Type using the default topic name. The default topic name is provided by the Self::topic_name function.

Arguments

• participant - The participant handle onto which this topic should be created
• maybe_topic_prefix - An additional prefix to be added to the topic name. This can be None
• maybe_qos - A QoS structure for this topic. The Qos is optional
• maybe_listener - A listener to use on this topic. The listener is optional

pub fn create_sample_buffer(len: usize) -> SampleBuffer<HeaderFixedSize>

Create a sample buffer for storing an array of samples You can pass the sample buffer into a read to read multiple samples. Multiple samples are useful when you have one or more keys in your topic structure. Each value of the key will result in the storage of another sample.
