Macro http 

macro_rules! http {
    ($client:expr) => { ... };
    ($client:expr, label = $label:expr) => { ... };
}

Wrap an HTTP client so every request it sends is timed and reported in the http section, keyed by normalized endpoint.

For reqwest::Client this returns the matching reqwest-middleware ClientWithMiddleware (spelled hotpath::wrap::reqwest::Client for feature-independent type names). For a ureq ConfigBuilder it returns the same builder with hotpath’s middleware appended. With the hotpath feature disabled the argument is returned unchanged.

Optional parameter: label (prefixes every endpoint key).

Examples

let client = hotpath::http!(reqwest::Client::new());
let client = hotpath::http!(reqwest::Client::new(), label = "github");

// Normal reqwest usage from here on:
let resp = client.get("https://api.example.com/users/1").send().await?;

// ureq: instrument the config builder before building the agent.
let agent: ureq::Agent = hotpath::http!(ureq::Agent::config_builder())
    .build()
    .new_agent();
let resp = agent.get("https://api.example.com/users/1").call()?;
