Struct FdPathMap 

Source 
pub struct FdPathMap {
    pub preopens: Vec<(String, PathBuf)>,
    pub by_rep: HashMap<u32, PathBuf>,
}
Expand description

Tracks the host path associated with each open filesystem descriptor, plus the configured preopen list (guest path → host path) used to fill in the map lazily the first time the guest calls get-directories.
