Struct nix::dir::Dir

pub struct Dir(_);

An open directory.

This is a lower-level interface than std::fs::ReadDir. Notable differences:

• can be opened from a file descriptor (as returned by openat, perhaps before knowing if the path represents a file or directory).
• implements AsRawFd, so it can be passed to fstat, openat, etc. The file descriptor continues to be owned by the Dir, so callers must not keep a RawFd after the Dir is dropped.
• can be iterated through multiple times without closing and reopening the file descriptor. Each iteration rewinds when finished.
• returns entries for . (current directory) and .. (parent directory).
• returns entries’ names as a CStr (no allocation or conversion beyond whatever libc does).

Implementations

impl Dir

pub fn open<P: ?Sized + NixPath>(
    path: &P,
    oflag: OFlag,
    mode: Mode
) -> Result<Self>

Opens the given path as with fcntl::open.

pub fn openat<P: ?Sized + NixPath>(
    dirfd: RawFd,
    path: &P,
    oflag: OFlag,
    mode: Mode
) -> Result<Self>

Opens the given path as with fcntl::openat.

pub fn from<F: IntoRawFd>(fd: F) -> Result<Self>

Converts from a descriptor-based object, closing the descriptor on success or failure.

pub fn from_fd(fd: RawFd) -> Result<Self>

Converts from a file descriptor, closing it on success or failure.

pub fn iter(&mut self) -> Iter<'_>

Returns an iterator of Result<Entry> which rewinds when finished.
