Macro spawn 

spawn!() { /* proc-macro */ }

Spawns a task within the current scope.

The spawn! macro expands to [Scope::spawn_registered], so it requires ambient __state and __cx bindings in addition to the target Scope.

The easiest supported path is to use it inside scope!(..., state: ..., { ... }).

Syntax

spawn!(async { /* work */ })
spawn!(async move { /* work with captured values */ })

Returns

A TaskHandle that can be awaited to get the task’s result.

Example

let handle = spawn!(async {
    expensive_computation().await
});
let result = handle.await;
