Struct fm::preview::Directory

pub struct Directory {
    pub content: Vec<(String, ColoredString)>,
    pub tree: Tree,
    pub selected_index: usize,
    /* private fields */
}

Display a tree view of a directory. The “tree view” is calculated recursively. It may take some time if the directory has a lot of children.

Fields

content: Vec<(String, ColoredString)>

tree: Tree

selected_index: usize

Implementations

impl Directory

pub fn new( path: &Path, users_cache: &UsersCache, colors: &Colors, filter_kind: &FilterKind, show_hidden: bool, max_depth: Option<usize> ) -> FmResult<Self>

Creates a new tree view of the directory. We only hold the result here, since the tree itself has now usage atm.

pub fn empty(path: &Path, users_cache: &UsersCache) -> FmResult<Self>

Creates an empty directory preview.

pub fn clear(&mut self)

Reset the attributes to default one and free some unused memory.

pub fn len(&self) -> usize

Number of displayed lines.

pub fn is_empty(&self) -> bool

True if there’s no lines in preview.

pub fn select_root(&mut self, colors: &Colors) -> FmResult<()>

Select the root node and reset the view.

pub fn unselect_children(&mut self)

Unselect every child node.

pub fn select_next(&mut self, colors: &Colors) -> FmResult<()>

Select the “next” element of the tree if any. This is the element immediatly below the current one.

pub fn select_prev(&mut self, colors: &Colors) -> FmResult<()>

Select the previous sibling if any. This is the element immediatly below the current one.

pub fn page_up(&mut self, colors: &Colors) -> FmResult<()>

Move up 10 times.

pub fn page_down(&mut self, colors: &Colors) -> FmResult<()>

Move down 10 times

pub fn update_tree_position_from_index( &mut self, colors: &Colors ) -> FmResult<()>

Update the position of the selected element from its index.

pub fn select_first_child(&mut self, colors: &Colors) -> FmResult<()>

Select the first child, if any.

pub fn select_parent(&mut self, colors: &Colors) -> FmResult<()>

Select the parent of current node.

pub fn go_to_bottom_leaf(&mut self, colors: &Colors) -> FmResult<()>

Select the last leaf of the tree (ie the last line.)

pub fn make_preview(&mut self, colors: &Colors)

Make a preview of the tree.

pub fn calculate_tree_window(&self, height: usize) -> (usize, usize, usize)

Calculates the top, bottom and lenght of the view, depending on which element is selected and the size of the window used to display.
