Function trace_lazy 

pub fn trace_lazy<F>(category: &str, message_fn: F)
where
    F: FnOnce() -> String,

Trace function with lazy message evaluation

Only evaluates the message function if tracing is enabled. This is useful for expensive message formatting that should be avoided when tracing is disabled.

Examples

use command_stream::trace::trace_lazy;

trace_lazy("ProcessRunner", || {
    format!("Expensive computation result: {}", 42)
});
