Struct miri::shims::unix::fs::DirHandler

pub struct DirHandler {
    streams: FxHashMap<u64, OpenDir>,
    next_id: u64,
}

Fields

streams: FxHashMap<u64, OpenDir>

Directory iterators used to emulate libc “directory streams”, as used in opendir, readdir, and closedir.

When opendir is called, a directory iterator is created on the host for the target directory, and an entry is stored in this hash map, indexed by an ID which represents the directory stream. When readdir is called, the directory stream ID is used to look up the corresponding ReadDir iterator from this map, and information from the next directory entry is returned. When closedir is called, the ReadDir iterator is removed from the map.

next_id: u64

ID number to be used by the next call to opendir

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
