Struct broot::tree::Tree

pub struct Tree {
    pub lines: Box<[TreeLine]>,
    pub selection: usize,
    pub options: TreeOptions,
    pub scroll: usize,
    pub nb_gitignored: u32,
    pub total_search: bool,
    pub git_status: ComputationResult<TreeGitStatus>,
}

The tree which may be displayed, with onle line per visible line of the panel.

In the tree structure, every “node” is just a line, there’s no link from a child to its parent or from a parent to its children.

Fields

lines: Box<[TreeLine]>

selection: usize

options: TreeOptions

scroll: usize

nb_gitignored: u32

total_search: bool

git_status: ComputationResult<TreeGitStatus>

Implementations

impl Tree

pub fn refresh(
    &mut self,
    page_height: usize,
    con: &AppContext
) -> Result<(), TreeBuildError>

rebuild the tree with the same root, height, and options

pub fn after_lines_changed(&mut self)

do what must be done after line additions or removals:

• sort the lines
• compute left branchs

pub fn has_branch(&self, line_index: usize, depth: usize) -> bool

pub fn move_selection(&mut self, dy: i32, page_height: usize, cycle: bool)

select another line

For example the following one if dy is 1.

pub fn try_scroll(&mut self, dy: i32, page_height: usize) -> bool

Scroll the desired amount and return true, or return false if it’s already at end or the tree fits the page

pub fn try_select_y(&mut self, y: usize) -> bool

try to select a line by index of visible line (works if y+scroll falls on a selectable line)

pub fn make_selection_visible(&mut self, page_height: usize)

pub fn selected_line(&self) -> &TreeLine

pub fn root(&self) -> &PathBuf

pub fn try_select_best_match(&mut self)

select the line with the best matching score

pub fn try_select_path(&mut self, path: &Path) -> bool

return true when we could select the given path

pub fn try_select_first(&mut self) -> bool

pub fn try_select_last(&mut self, page_height: usize) -> bool

pub fn try_select_previous_same_depth(&mut self, page_height: usize) -> bool

pub fn try_select_next_same_depth(&mut self, page_height: usize) -> bool

pub fn try_select_previous_match(&mut self, page_height: usize) -> bool

pub fn try_select_next_match(&mut self, page_height: usize) -> bool

pub fn has_dir_missing_sum(&self) -> bool

pub fn is_missing_git_status_computation(&self) -> bool

pub fn fetch_regular_file_sums(&mut self)

fetch the file_sums of regular files (thus avoiding the long computation which is needed for directories)

pub fn fetch_some_missing_dir_sum(&mut self, dam: &Dam, con: &AppContext)

compute the file_sum of one directory

To compute the size of all of them, this should be called until has_dir_missing_sum returns false

pub fn total_sum(&self) -> FileSum

compute and return the size of the root

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a copy 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.
