Struct surf::http::trace::ServerTiming

pub struct ServerTiming { /* fields omitted */ }

Metrics and descriptions for the given request-response cycle.

Specifications

• Server Timing (Working Draft)

Examples

use http_types::Response;
use http_types::trace::{ServerTiming, Metric};

let mut timings = ServerTiming::new();
timings.push(Metric::new("server".to_owned(), None, None)?);

let mut res = Response::new(200);
timings.apply(&mut res);

let timings = ServerTiming::from_headers(res)?.unwrap();
let entry = timings.iter().next().unwrap();
assert_eq!(entry.name(), "server");

Implementations

impl ServerTiming

pub fn new() -> ServerTiming

Create a new instance of ServerTiming.

pub fn from_headers(
    headers: impl AsRef<Headers>
) -> Result<Option<ServerTiming>, Error>

Create a new instance from headers.

pub fn apply(&self, headers: impl AsMut<Headers>)

Sets the Server-Timing header.

pub fn name(&self) -> HeaderName

pub fn value(&self) -> HeaderValue

Get the HeaderValue.

pub fn push(&mut self, entry: Metric)

Push an entry into the list of entries.

pub fn iter(&self) -> Iter<'_>

An iterator visiting all server timings.

pub fn iter_mut(&mut self) -> IterMut<'_>
