Function prometheus_http_query::label_names

pub async fn label_names(
    host: &str,
    selectors: Option<Vec<Selector<'_>>>,
    start: Option<i64>,
    end: Option<i64>
) -> Result<Vec<String>, Error>

Retrieve all label names (or use Selectors to select time series to read label names from).

This is just a convenience function for one-off requests, see Client::label_names.

use prometheus_http_query::{label_names, Error};

#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<(), Error> {
    let response = label_names("http://localhost:9090", None, None, None).await;

    assert!(response.is_ok());

    Ok(())
}
