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_node_or_parent(&self) -> Result<&Node>

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
