Struct InfluxLineProtocol 

pub struct InfluxLineProtocol { /* private fields */ }

Encodes MetricEvents into InfluxDB line protocol format.

The field key used for the metric value is configured at construction time. It defaults to "value".

Output format (with tags):

measurement,tag1=val1,tag2=val2 field_key=value 1700000000000000000\n

Output format (no tags):

measurement field_key=value 1700000000000000000\n

Timestamp is nanoseconds since the Unix epoch.

Characters ,, , and = are escaped with a backslash in measurement names and tag keys/values.

When precision is set, metric values are formatted to the specified number of decimal places.

Implementations

impl InfluxLineProtocol

pub fn new(field_key: Option<String>, precision: Option<u8>) -> Self

Create a new InfluxLineProtocol encoder.

field_key sets the InfluxDB field key for the metric value. If None, defaults to "value". The field key is escaped and stored at construction time to avoid per-event work.

precision optionally limits the number of decimal places in metric values. None preserves full f64 precision (default behavior).

Trait Implementations

impl Encoder for InfluxLineProtocol

fn encode_metric( &self, event: &MetricEvent, buf: &mut Vec<u8>, ) -> Result<(), SondaError>

Encode a metric event into InfluxDB line protocol format.

Appends a complete line to buf. The buffer is not cleared before writing. Writes into the caller-provided buffer to minimize allocations.

fn encode_log( &self, _event: &LogEvent, _buf: &mut Vec<u8>, ) -> Result<(), SondaError>

Encode a log event into the provided buffer.
