Struct Kafka 

pub struct Kafka {
    pub brokers: Vec<String>,
    pub topic: String,
    pub message_timeout_ms: u32,
    pub delivery_wait_secs: u64,
    /* private fields */
}

Kafka client configuration for audit message production.

The [FutureProducer] is lazily created on the first call to Audit::produce_message and reused for all subsequent calls via an internal OnceLock.

Fields

brokers: Vec<String>

Bootstrap broker list, e.g. vec!["kafka.example.com:9092"].

topic: String

Kafka topic that audit messages are published to.

message_timeout_ms: u32

librdkafka message.timeout.ms: how long a queued audit message tries to deliver before being dropped.

delivery_wait_secs: u64

How long produce_message blocks waiting for delivery confirmation. Zero (default) is fire-and-forget.

Implementations

impl Kafka

pub fn new(brokers: Vec<String>, topic: String) -> Self

Create a new Kafka instance with the given broker list and topic name. Uses the crate-internal message.timeout.ms and delivery-wait defaults (5000ms and fire-and-forget, respectively); for non-default values, deserialize a Kafka from server.toml’s [auditor.kafka] block instead.

The actual FutureProducer is built lazily on the first Audit::produce_message call, so this constructor is cheap and infallible.

Trait Implementations

impl Audit for Kafka

async fn produce_message(&self, data: &[u8]) -> Result<(), MantaError>

Publish a single audit message payload. Implementations are expected to be fire-and-forget — failures should be logged but not propagated to the caller, since audit failures must not abort the outer operation.

impl Clone for Kafka

fn clone(&self) -> Self

Clone the configuration only; the cached producer is not cloned and will be lazily recreated.

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

Performs copy-assignment from source.

impl Debug for Kafka

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Kafka

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Kafka

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
