influxdb 0.7.2

InfluxDB Driver for Rust
Documentation

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. 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?; // Let's see if the data we wrote is there  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", "use-serde", "reqwest-client"] }

  • hyper (through surf), use this if you need tokio 0.2 compatibility

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

  • curl, using libcurl

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

  • async-h1 with native TLS (OpenSSL)

    influxdb = { version = "0.7.2", default-features = false,features = ["derive", "use-serde", "h1-client"] }

  • async-h1 with rustls

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

  • WebAssembly’s window.fetch, via web-sys and wasm-bindgen

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