Unofficial InfluxDB Driver for Rust

This library is a work in progress. Although we've been using it in production at OpenVelo, we're prioritized features that fit our use cases. This means a feature you might need is not implemented yet or could be handled better.

Pull requests are always welcome.

Currently Supported Features

• Reading and Writing to InfluxDB
• Optional Serde Support for Deserialization

Planned Features

• Running multiple queries in one request (e.g. SELECT * FROM weather_berlin; SELECT * FROM weather_london)
• Read Query Builder instead of supplying raw queries
• Authentication against InfluxDB
• Methods for setting time and time precision in a query

Quickstart

Add the following to your Cargo.toml

influxdb = "0.0.1"

For an example with using Serde deserialization, please refer to serde_integration

use influxdb::query::InfluxDbQuery;
use influxdb::client::InfluxDbClient;
use serde::Deserialize;
use tokio::runtime::current_thread::Runtime;

// Create a InfluxDbClient with URL `http://localhost:8086`
// and database name `test`
let client = InfluxDbClient::new("http://localhost:8086", "test");

// Let's write something to InfluxDB. First we're creating a
// InfluxDbWriteQuery to write some data.
// This creates a query which writes a new measurement into a series called `weather`
let write_query = InfluxDbQuery::write_query("weather")
    .add_field("temperature", 82);

// Since this library is async by default, we're going to need a Runtime,
// which can asynchonously run our query.
// The [tokio](https://crates.io/crates/tokio) crate lets us easily create a new Runtime.
let mut rt = Runtime::new().expect("Unable to create a runtime");

// To actually submit the data to InfluxDB, the `block_on` method can be used to
// halt execution of our program until it has been completed.
let write_result = rt.block_on(client.query(write_query));
assert!(write_result.is_ok(), "Write result was not okay");

// Reading data is as simple as writing. First we need to create a query
let read_query = InfluxDbQuery::raw_read_query("SELECT _ FROM weather");

// Again, we're blocking until the request is done
let read_result = rt.block_on(client.query(read_query));

assert!(read_result.is_ok(), "Read result was not ok");

// We can be sure the result was successful, so we can unwrap the result to get
// the response String from InfluxDB
println!("{}", read_result.unwrap());
