Struct Tree 

pub struct Tree { /* private fields */ }

A FileSystem tree of nodes. Internally it’s a wrapper around an std::collections::HashMap<PathBuf, Node> It also holds informations about the required height of the tree.

Implementations

impl Tree

pub fn root_path(&self) -> &Path

Root path of the tree.

pub fn selected_path(&self) -> &Path

Selected path

pub fn selected_path_or_parent(&self) -> Result<PathBuf>

Returns an existing path which is either the selected path or its first existing parent.

Errors

Will fail if the selected node doesn’t exists or has no parent. It should never be the case since we can’t rename or delete the root /.

pub fn selected_node(&self) -> Option<&Node>

Selected node

pub fn directory_of_selected(&self) -> Option<&Path>

The folder containing the selected node. Itself if selected is a directory.

pub fn selected_path_relative_to_root(&self) -> Result<&Path>

Relative path of selected from rootpath.

pub fn len(&self) -> usize

Number of nodes

pub fn display_len(&self) -> usize

pub fn is_empty(&self) -> bool

True if there’s no node.

pub fn is_on_root(&self) -> bool

True if selected is root.

pub fn page_up(&mut self)

pub fn page_down(&mut self)

pub fn toggle_fold(&mut self)

Fold selected node

pub fn fold_all(&mut self)

Fold all node from root to end

pub fn unfold_all(&mut self)

Unfold all node from root to end

pub fn displayable(&self) -> &TreeLines

pub fn paths(&self) -> Vec<&Path>

Vector of Path of nodes.

pub fn flag_all(&self, flagged: &mut Flagged)

pub fn has_modified_dirs(&self) -> bool

True if any directory (not symlink to a directory) has been modified less than 10 seconds ago.

pub fn selected_is_last(&self) -> bool

pub fn path_from_index(&self, index: usize) -> Result<PathBuf>

pub fn lines_enum_skip_take( &self, window: &ContentWindow, ) -> Take<Skip<Enumerate<Iter<'_, TLine>>>>

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tree

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

Formats the value using the given formatter.

impl Default for Tree

fn default() -> Self

Returns the “default value” for a type.

impl Go for Tree

fn go(&mut self, to: To<'_>)

Select another element from a tree.

impl IndexToIndex<TLine> for Tree

fn index_to_index(&self) -> Chain<Skip<Iter<'_, TLine>>, Take<Iter<'_, TLine>>>

Iterate over line from current index to bottom then from top to current index.

Useful when going to next match in search results
