Enum LayoutTree 

pub enum LayoutTree {
    Leaf {
        surface_id: SurfaceId,
    },
    Split {
        axis: Axis,
        children: Vec<LayoutTree>,
        weights: Vec<f64>,
    },
    Tabs {
        active_id: SurfaceId,
        children: Vec<SurfaceId>,
    },
    Freeform {
        surface_id: SurfaceId,
    },
}

Authoritative layout produced by the Host (output), referencing surfaces only by id. Overlay/float surfaces never appear here.

Implementations

impl LayoutTree

pub fn surface_ids(&self) -> Vec<SurfaceId>

Collect every surfaceId referenced by the tree.

pub fn validate(&self) -> Result<(), String>

Structural invariants: tabs.activeId ∈ children, split weights match children and are positive, splits have ≥2 children.

Trait Implementations

impl Clone for LayoutTree

fn clone(&self) -> LayoutTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutTree

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LayoutTree

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for LayoutTree

fn eq(&self, other: &LayoutTree) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LayoutTree

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
