Struct fluvio::TopicProducer [−][src]
An interface for producing events to a particular topic
A TopicProducer
allows you to send events to the specific
topic it was initialized for. Once you have a TopicProducer
,
you can send events to the topic, choosing which partition
each event should be delivered to.
Implementations
impl TopicProducer
[src]
pub async fn send<K, V>(&self, key: K, value: V) -> Result<(), FluvioError> where
K: AsRef<[u8]>,
V: AsRef<[u8]>,
[src]
K: AsRef<[u8]>,
V: AsRef<[u8]>,
Sends a key/value record to this producer’s Topic.
The partition that the record will be sent to is derived from the Key.
Example
producer.send("Key", "Value").await?;
pub async fn send_record<B: AsRef<[u8]>>(
&self,
buffer: B,
partition: i32
) -> Result<(), FluvioError>
[src]
&self,
buffer: B,
partition: i32
) -> Result<(), FluvioError>
Sends an event to a specific partition within this producer’s topic
Example
let partition = 0; producer.send_record("Hello, Fluvio!", partition).await?;
