Method new

src/fs/raw_dir.rs:128–142

Create a new iterator from the given file descriptor and buffer. Note: the buffer size may be trimmed to accommodate alignment requirements. # Examples ## Simple but non-portable These examples are non-portable, because file systems may not have a maximum file name length. If you can make assumptions that bound this length, then these examples may suffice. Using the heap: ``` # use std::mem:

(fd: Fd, buf: &'buf mut [MaybeUninit<u8>])

    /// }
    /// ```
    pub fn new(fd: Fd, buf: &'buf mut [MaybeUninit<u8>]) -> Self {
        Self {
            fd,
            buf: {
                let offset = buf.as_ptr().align_offset(align_of::<linux_dirent64>());
                if offset < buf.len() {
                    &mut buf[offset..]
                } else {
                    &mut []
                }
            },
            initialized: 0,
            offset: 0,
        }
    }
}
