impl RootDirs

pub fn len(&self) -> usize

Returns the number of directory-tree namespaces in the image.

pub fn is_empty(&self) -> bool

Returns whether the image contains no directory-tree namespaces.

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

Iterates over every directory-tree namespace in descriptor order.

pub fn get(&self, ty: EntryType) -> Option<RootDir>

Finds the root whose entry type exactly matches ty.

pub fn try_best_choice(&self) -> Option<RootDir>

Selects the most useful directory-tree namespace, if one exists.

pub fn best_choice(&self) -> RootDir

Selects the most useful directory-tree namespace.

Panics

Panics if the ISO image contains no directory trees. Use Self::try_best_choice when handling a potentially empty collection.
