Rust utility for efficiently writing metrics to a running InfluxDB instance.

Example

```rust use influxivecore::Metric; use influxivewriter::*;

let writer = InfluxiveWriter::withtokenauth( InfluxiveWriterConfig::default(), "http://127.0.0.1:8086", "my.bucket", "my.token", );

writer.writemetric( Metric::new( std::time::SystemTime::now(), "my.metric", ) .withfield("value", 3.14) .with_tag("tag", "test-tag") ); ```
