InfluxDBClient-rs

A easy-use client to influxdb

Overview

This is an InfluxDB driver for Rust.

Status

This project has been able to run properly, PR is welcome.

Usage

Use

[dependencies]
influx_db_client = "^0.4.0"

http

use influx_db_client::{
    Client, Point, Points, Value, Precision, point, points
};
use tokio;

fn main() {
    // default with "http://127.0.0.1:8086", db with "test"
    let client = Client::default().set_authentication("root", "root");

    let point = point!("test1")
        .add_field("foo", Value::String("bar".to_string()))
        .add_field("integer", Value::Integer(11))
        .add_field("float", Value::Float(22.3))
        .add_field("'boolean'", Value::Boolean(false));

    let point1 = Point::new("test1")
        .add_tag("tags", Value::String(String::from("\\\"fda")))
        .add_tag("number", Value::Integer(12))
        .add_tag("float", Value::Float(12.6))
        .add_field("fd", Value::String("'3'".to_string()))
        .add_field("quto", Value::String("\\\"fda".to_string()))
        .add_field("quto1", Value::String("\"fda".to_string()));

    let points = points!(point1, point);

    tokio::runtime::Runtime::new().unwrap().block_on(async move {
        // if Precision is None, the default is second
        // Multiple write
        client.write_points(points, Some(Precision::Seconds), None).await.unwrap();

        // query, it's type is Option<Vec<Node>>
        let res = client.query("select * from test1", None).await.unwrap();
        println!("{:?}", res.unwrap()[0].series)
    });
}

udp

use influx_db_client::{UdpClient, Point, Value, point};

fn main() {
    let mut udp = UdpClient::new("127.0.0.1:8089");
    udp.add_host("127.0.0.1:8090");

    let point = point!("test").add_field("foo", Value::String(String::from("bar")));

    udp.write_point(point).unwrap();
}

Compatibility

This is the API Document, it may apply to version 1.0 or higher.

I have tested it in version 1.0.2/1.3.5/1.5.

Thanks

Because influent seems to have no longer updated, and only support to the 0.9 version. I read influent.rs and influxdb-python source, and then try to write a library for 1.0+ version for support for my own use.
