Macro future 

macro_rules! future {
    ($fut:expr) => { ... };
    ($fut:expr, label = $label:expr) => { ... };
    ($fut:expr, log = true) => { ... };
    ($fut:expr, label = $label:expr, log = true) => { ... };
    ($fut:expr, log = true, label = $label:expr) => { ... };
}

Instrument a future to inspect future’s lifecycle events.

Optional parameters: label, log = true. log = true requires Debug on the output type and prints Ready(value).

Examples

use hotpath::future;

// Without logging (works with any output type)
let result = future!(async { NoDebugType::new() }).await;

// With logging (requires Debug on output type)
let result = future!(async { 42 }, log = true).await;
