Struct broot::display::DisplayableTree

pub struct DisplayableTree<'a, 's, 't> {
    pub app_state: Option<&'a AppState>,
    pub tree: &'t Tree,
    pub skin: &'s StyleMap,
    pub area: Area,
    pub in_app: bool,
    pub ext_colors: &'s ExtColorMap,
}

A tree wrapper which can be used either

• to write on the screen in the application,
• or to write in a file or an exported string. Using it in the application (with in_app true) means that
• the selection is drawn
• a scrollbar may be drawn
• the empty lines will be erased

Fields

app_state: Option<&'a AppState>

tree: &'t Tree

skin: &'s StyleMap

area: Area

in_app: bool

ext_colors: &'s ExtColorMap

Implementations

impl<'a, 's, 't> DisplayableTree<'a, 's, 't>

pub fn out_of_app(
    tree: &'t Tree,
    skin: &'s StyleMap,
    ext_colors: &'s ExtColorMap,
    width: u16,
    height: u16
) -> DisplayableTree<'a, 's, 't>

pub fn write_root_line<'w, W: Write>(
    &self,
    cw: &mut CropWriter<'w, W>,
    selected: bool
) -> Result<(), ProgramError>

pub fn extend_line_bg<'w, W: Write>(
    &self,
    cw: &mut CropWriter<'w, W>,
    selected: bool
) -> Result<(), ProgramError>

if in app, extend the background till the end of screen row

pub fn write_on<W: Write>(&self, f: &mut W) -> Result<(), ProgramError>

write the whole tree on the given W
