Macro compute_medium 

macro_rules! compute_medium {
    ($expr:expr) => { ... };
    ($pool:expr, $expr:expr) => { ... };
}

Execute a medium compute task (100μs-1ms) with intelligent scheduling.

This macro first tries to use thread-local context if available (on Tokio worker threads). If no thread-local context, it requires a pool parameter.

Example

// With thread-local context (on worker thread)
let result = compute_medium!({
    (0..1000).map(|i| i * 2).sum::<i32>()
}).await;

// Or with explicit pool (fallback)
let result = compute_medium!(pool, {
    (0..1000).map(|i| i * 2).sum::<i32>()
}).await;
