Crate influx_db_client
source ·Expand description
InfluxDB Client
InfluxDB is an open source time series database with no external dependencies. It’s useful for recording metrics, events, and performing analytics.
Usage
http
#[macro_use]
extern crate influx_db_client;
use influx_db_client::{Client, Point, Points, Value, Precision};
fn main() {
// default with "http://127.0.0.1:8086", db with "test"
let client = Client::default().set_authentication("root", "root");
let mut point = point!("test1");
point
.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()))
.to_owned();
let points = points!(point1, point);
// if Precision is None, the default is second
// Multiple write
let _ = client.write_points(points, Some(Precision::Seconds), None).unwrap();
// query, it's type is Option<Vec<Node>>
let res = client.query("select * from test1", None).unwrap();
println!("{:?}", res.unwrap()[0].series)
}
udp
#[macro_use]
extern crate influx_db_client;
use influx_db_client::{UdpClient, Point, Value};
fn main() {
let mut udp = UdpClient::new("127.0.0.1:8089");
udp.add_host("127.0.0.1:8090");
let mut point = point!("test");
point.add_field("foo", Value::String(String::from("bar")));
let _ = udp.write_point(point).unwrap();
}
