Struct LayerTree 

pub struct LayerTree {
    pub layers: Vec<Layer>,
    pub root: LayerNode,
    pub unreachable: Vec<i64>,
}

All layers and the tree they form.

Fields

layers: Vec<Layer>

Every row of Layer, in table order.

root: LayerNode

The root folder and everything reachable from it.

unreachable: Vec<i64>

Layers not reachable from the root (CSP files have none).

Implementations

impl LayerTree

pub fn read(connection: &Connection, root_id: i64) -> Result<Self>

Reads Layer and links the tree from the root folder root_id (Canvas.CanvasRootFolder). Fails on a cycle, a missing link or a tree deeper than 256.

pub fn get(&self, main_id: i64) -> Option<&Layer>

The layer with this MainId.

pub fn flatten(&self) -> Vec<(&Layer, usize)>

(layer, depth) in palette order: parents first, siblings bottom to top.

Trait Implementations

impl Clone for LayerTree

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayerTree

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

Formats the value using the given formatter.
