Function prometheus_http_query::aggregations::quantile

pub fn quantile<'a>(
    vector: InstantVector, 
    labels: Option<Aggregate<'a>>, 
    parameter: f64
) -> InstantVector

Use the quantile aggregation operator on an instant vector.

use prometheus_http_query::{Selector, InstantVector, Aggregate};
use prometheus_http_query::aggregations::quantile;
use std::convert::TryInto;

fn main() -> Result<(), prometheus_http_query::Error> {
    let vector: InstantVector = Selector::new()
        .metric("node_cpu_seconds_total")?
        .try_into()?;

    let result = quantile(vector, Some(Aggregate::By(&["cpu", "mode"])), 0.1);

    assert_eq!(result.to_string(), String::from("quantile by (cpu,mode) (0.1, node_cpu_seconds_total)"));

    Ok(())
