Macro trace_operation

macro_rules! trace_operation {
    ($op_name:expr, $result:expr) => { ... };
}

Wraps an operation with start/end logging.

Logs operation lifecycle at DEBUG level and returns the operation’s result. Ideal for timing and monitoring critical sections.

Examples

let data = trace_operation!("process_batch", {
    // CPU/GPU intensive work
    vec![0u8; 1024]
});
