Build Status Coverage Report Documentation Status Build with Rust Minimum Rust Version: 1.65

Pull requests are always welcome. See Contributing and Code of Conduct. For a list of past changes, see CHANGELOG.md.

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)
  • Writing single or multiple measurements in one request (e.g. WriteQuery or Vec<WriteQuery> argument)
  • Authenticated and unauthenticated connections
  • async/await support
  • #[derive(InfluxDbWriteable)] derive macro for writing / reading into structs
  • GROUP BY support
  • Tokio and async-std support (see example below) or available backends
  • Swappable HTTP backends (see below)

Quickstart

Add the following to your Cargo.toml

influxdb = { version = "0.7.2", features = ["derive"] }

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

use chrono::{DateTime, Utc};
use influxdb::{Client, Error, InfluxDbWriteable, ReadQuery, Timestamp};

#[tokio::main]
// or #[async_std::main] if you prefer
async fn main() -> Result<(), Error> {
    // 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,
        #[influxdb(tag)]
        wind_direction: String,
    }

    // Let's write some data into a measurement called `weather`
    let weather_readings = vec![
        WeatherReading {
            time: Timestamp::Hours(1).into(),
            humidity: 30,
            wind_direction: String::from("north"),
        }
        .into_query("weather"),
        WeatherReading {
            time: Timestamp::Hours(2).into(),
            humidity: 40,
            wind_direction: String::from("west"),
        }
        .into_query("weather"),
    ];

    client.query(weather_readings).await?;

    // Read back all records
    let read_query = ReadQuery::new("SELECT * FROM weather");

    let read_result = client.query(read_query).await?;
    println!("{}", read_result);
    Ok(())
}

For further examples, check out the integration tests in tests/integration_tests.rs in the repository.

Choice of HTTP backend

To communicate with InfluxDB, you can choose the HTTP backend to be used configuring the appropriate feature. We recommend sticking with the default reqwest-based client, unless you really need async-std compatibility.

  • hyper (through reqwest, used by default), with rustls

    influxdb = { version = "0.7.2", features = ["derive"] }
    
  • hyper (through reqwest), with native TLS (OpenSSL)

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "reqwest-client-native-tls"] }
    
  • hyper (through reqwest), with vendored native TLS (OpenSSL)

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "reqwest-client-native-tls-vendored"] }
    
  • hyper (through surf), use this if you need tokio 0.2 compatibility

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "hyper-client"] }
    
  • curl, using libcurl

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "curl-client"] }
    
  • async-h1 with native TLS (OpenSSL)

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "h1-client"] }
    
  • async-h1 with rustls

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "h1-client-rustls"] }
    
  • WebAssembly’s window.fetch, via web-sys and wasm-bindgen

    influxdb = { version = "0.7.2", default-features = false, features = ["derive", "serde", "wasm-client"] }
