Crate hitrace

HiTrace

Safe bindings for the HiTrace tracing system on OpenHarmony. This crate does nothing if not compiled for OpenHarmony (target_env = ohos).

Usage

HiTrace allows tracing Spans in a synchronous and stack based fashion.

Examples

fn load_website() {
    start_trace(&c"step1");
    step1();
    finish_trace();
    start_trace(&CString::new("step2").unwrap());
    step2();
    finish_trace();
}
start_trace(&c"LoadingWebsite");
load_website();
finish_trace();
