Struct DirStream 

struct DirStream {
    read_dir: ReadDir,
    fd_num: i32,
    fd_id: FdId,
    special_entries: Vec<&'static str>,
    entry: Option<Pointer>,
}

An open directory stream, tracked by DirTable.

Fields

read_dir: ReadDir

The directory reader on the host.

fd_num: i32

An FD number for the same handle. Unix directory streams have an “underlying FD” that can be exposed; this is that FD. We also store the FD ID to catch cases where the FD was closed and a different one re-opened.

fd_id: FdId

special_entries: Vec<&'static str>

The “special” entries that must still be yielded by the iterator. Used for . and ...

entry: Option<Pointer>

The most recent entry returned by readdir(). Will be freed by the next call.

Implementations

impl DirStream

fn new(read_dir: ReadDir, fd_num: i32, fd_id: FdId) -> Self

fn next_host_entry(&mut self) -> Option<Result<Either<DirEntry, &'static str>>>

Trait Implementations

impl Debug for DirStream

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
