Struct slos_filesystem::impls::overlayfs::OverlayFilesystemPath

pub struct OverlayFilesystemPath<'a, 'base, 'overlay> {
    pub inner: Arc<OverlayFilesystemInner<'a, 'base, 'overlay>>,
    pub path: Vec<String>,
    // some fields omitted
}

Fields

inner: Arc<OverlayFilesystemInner<'a, 'base, 'overlay>>

path: Vec<String>

Implementations

impl<'a, 'base, 'overlay> OverlayFilesystemPath<'a, 'base, 'overlay>

pub fn new_from_inner(
    inner: Arc<OverlayFilesystemInner<'a, 'base, 'overlay>>
) -> Self

pub fn is_file(&self) -> bool

Is this node a file?

pub fn is_directory(&self) -> bool

Is this node a directory?

pub fn try_get_inner_node(
    &mut self,
    ignore_root: bool
) -> Option<&mut dyn FsNode>

Try to get the inner node for the current path.

If ignore_root is true, this ignores filesystem roots when finding a return value. If ignore_root is false, and we have an empty path, this will return the filesystem root for the overlay.
