This library is a work in progress. This means a feature you might need is not implemented yet or could be handled better.
Pull requests are always welcome. See Contributing and Code of Conduct.
Currently Supported Features
- Reading and Writing to InfluxDB
- Optional Serde Support for Deserialization
- Running multiple queries in one request (e.g.
SELECT * FROM weather_berlin; SELECT * FROM weather_london
) - Authenticated and Unauthenticated Connections

Quickstart
Add the following to your Cargo.toml
influxdb = { version = "0.3.0", features = ["derive"] }
For an example with using Serde deserialization, please refer to serde_integration
use influxdb::{Client, Query, Timestamp}; use influxdb::InfluxDbWriteable; use chrono::{DateTime, Utc}; #[async_std::main] // or #[tokio::main] if you prefer async fn main() { // Connect to db `test` on `http://localhost:8086` let client = Client::new("http://localhost:8086", "test"); #[derive(InfluxDbWriteable)] struct WeatherReading { time: DateTime<Utc>, humidity: i32, #[tag] wind_direction: String, } // Let's write some data into a measurement called `weather` let weather_reading = WeatherReading { time: Timestamp::Hours(1).into(), humidity: 30, wind_direction: String::from("north"), }; let write_result = client .query(&weather_reading.into_query("weather")) .await; assert!(write_result.is_ok(), "Write result was not okay"); // Let's see if the data we wrote is there let read_query = Query::raw_read_query("SELECT * FROM weather"); let read_result = client.query(&read_query).await; assert!(read_result.is_ok(), "Read result was not ok"); println!("{}", read_result.unwrap()); }
