Detailed Description

Accessors for the running application's embedded metadata.

Provides information about the currently running firmware image, including version, project name, build timestamps, and ELF hash. All string accessors return views into static storage and do not allocate.

#include <idfxx/app>
 
auto ver = idfxx::app::version();       // e.g. "1.0.0"
auto name = idfxx::app::project_name(); // e.g. "my_project"
