Function prometheus_http_query::query

pub fn query(
    host: &str,
    query: impl Display
) -> Result<InstantQueryBuilder, Error>

Execute an instant query.

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

use prometheus_http_query::query;

#[tokio::main(flavor = "current_thread")]
async fn main() -> Result<(), anyhow::Error> {
    let q = "sum(prometheus_http_requests_total)";

    let response = query("http://localhost:9090", q)?.timeout(1000).get().await?;

    assert!(response.data().as_vector().is_some());

    // Or make a POST request.
    let response = query("http://localhost:9090", q)?.timeout(1000).post().await?;

    assert!(response.data().as_vector().is_some());

    Ok(())
}
