Struct LayoutSnapshot 

pub struct LayoutSnapshot { /* private fields */ }

Serializable snapshot of a LayoutRuntime for session persistence.

Strategy runtimes serialize the recipe (strategy config + panel kinds). Non-strategy runtimes serialize the tree topology.

Example

let mut rt = Layout::master_stack(["editor", "chat", "status"])
    .master_ratio(0.6).gap(1.0).into_runtime().unwrap();
let snapshot = rt.snapshot().unwrap();

// Serialize with any serde format:
// let json = serde_json::to_string(&snapshot).unwrap();

// Restore later:
let mut rt2 = panes::runtime::LayoutRuntime::from_snapshot(snapshot).unwrap();

Implementations

impl LayoutSnapshot

pub fn source(&self) -> &SnapshotSource

Returns the snapshot source: a strategy config, tree topology, or adaptive breakpoint set.

pub fn focused(&self) -> Option<&str>

Returns the kind of the focused panel at capture time, if any.

pub fn collapsed(&self) -> &[Box<str>]

Returns the kinds of all collapsed panels at capture time.

pub fn focused_key(&self) -> Option<PanelKey>

Sequence index of the focused panel for deterministic restore.

pub fn collapsed_keys(&self) -> &[PanelKey]

Sequence indices of collapsed panels for deterministic restore.

pub fn overlays(&self) -> &[SnapshotOverlay]

Returns the overlay definitions captured at snapshot time.

pub fn into_overlays(self) -> Vec<SnapshotOverlay>

Consumes the snapshot and returns the overlay definitions as an owned Vec.

Trait Implementations

impl Clone for LayoutSnapshot

fn clone(&self) -> LayoutSnapshot

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LayoutSnapshot

fn fmt(&self, f: &mut Formatter<'_>) -> Result
