Type Alias BoxFuture 

pub type BoxFuture<'a, T> = Pin<Box<dyn Future<Output = T> + Send + 'a>>;

Available on non-WebAssembly only.

A boxed future — the one future alias of the ppoppo family. Send on every target but wasm32, where the browser runs one thread and a JsFuture is never Send; a port held as dyn returns it, so one signature serves both targets.
