Struct Layout

pub struct Layout {
    pub tree: Tree<Pane>,
    pub popped: Vec<Pane>,
    pub undo: Vec<String>,
    pub redo: Vec<String>,
}

The whole layout: the docked tree plus panes currently popped out into their own windows.

Fields

tree: Tree<Pane>

popped: Vec<Pane>

undo: Vec<String>

The layout’s own undo history (serialised layouts): the layout is not the project, so it cannot ride the project’s snapshots. Never persisted, and 20 steps is plenty for “put that tab back”.

redo: Vec<String>

Implementations

impl Layout

pub fn default_layout() -> Self

pub fn new(tree: Tree<Pane>) -> Self

A layout around a tree, with an empty history.

pub fn to_json(&self) -> String

pub fn from_json(s: &str) -> Option<Self>

None on malformed / incompatible JSON (caller falls back to the default layout). A layout saved before round 3 knows nothing about Tools / Nodes / Mixer / Markers: rather than dropping four panes into the root as loose tabs, it is rejected here and the caller resets to the new default.

pub fn from_json_migrating(s: &str) -> Option<Self>

Same, but an explicitly saved profile is migrated instead of rejected: panes it predates are added to the root rather than making the whole profile unloadable.

pub fn is_visible(&self, pane: Pane) -> bool

Visible = docked in the tree (and not hidden) or popped out.

pub fn toggle(&mut self, pane: Pane)

Show (back where it was in the tree, or into the root when it is gone) or hide (invisible in the tree / close the popout).

pub fn reveal(&mut self, pane: Pane)

Make the pane visible (docked or popped) and, if it is a tab, the active one.

pub fn popout(&mut self, pane: Pane)

pub fn dock(&mut self, pane: Pane)

pub fn reset(&mut self)

pub fn push_undo(&mut self, snapshot: String)

Remember the arrangement snapshot was taken from (before the move), so Ctrl+Z can go back to it.

pub fn undo(&mut self) -> bool

pub fn redo(&mut self) -> bool

fn step(&mut self, undoing: bool) -> bool

fn insert_into_root(&mut self, pane: Pane)

A pane that fell out of the tree entirely (e.g. an old profile): add it as a new tab in the root.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Layout

Returns a copy of the value.
