cdylib的情况

fn main() {
    let dylib = unsafe { libloading::Library::new(dylib) }.expect("error loading dylib");
    let setup_logger: FnSetupLogger = unsafe { *dylib.get(b"setup_shared_logger_ref").unwrap() };
    let run: FnRun = unsafe { *dylib.get(b"run").unwrap() };
    let logger = SharedLogger::new();
    setup_logger(&logger);
    run("cdylib")
}

cdylib的情况

use tracing_shared::SharedLogger;

fn main() {
    let dylib = unsafe { libloading::Library::new(dylib) }.expect("error loading dylib");
    let setup_logger: FnSetupLogger = unsafe { *dylib.get(b"setup_shared_logger_ref").unwrap() };
    let run: FnRun = unsafe { *dylib.get(b"run").unwrap() };
    let logger = SharedLogger::new();
    setup_logger(&logger);
    run("cdylib")
}

dylib的情况
