//! Library for talking to InfluxDB //! //! This library is a work in progress. Although we've been using it in production at [OpenVelo](https://openvelo.org/), //! 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` //! //! ```toml //! influxdb = "0.0.1" //! ``` //! //! For an example with using Serde deserialization, please refer to [serde_integration](crate::integrations::serde_integration) //! //! ```rust,no_run //! use influxdb::query::{InfluxDbQuery, Timestamp}; //! 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(Timestamp::NOW, "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()); //! ``` //! //! For further examples, check out the Integration Tests in `tests/integration_tests.rs` //! in the repository. #[macro_use] extern crate failure; pub mod client; pub mod error; pub mod query; #[cfg(feature = "use-serde")] pub mod integrations { #[cfg(feature = "use-serde")] pub mod serde_integration; }
