Struct ModelLayers 

pub struct ModelLayers { /* private fields */ }

The generated model and the layers over it. Taking a setting off a layer brings back what the layer below says.

Implementations

impl ModelLayers

pub fn new(zero: ModelNode) -> Self

Layers over this generated model, all empty.

pub fn set( &mut self, layer: &ModelLayer, path: &[&str], name: &str, value: Json, )

A setting at this path of ids, on this layer.

pub fn clear(&mut self, layer: &ModelLayer, path: &[&str], name: &str)

Takes the setting off this layer, so the one below answers again.

pub fn put(&mut self, layer: &ModelLayer, difference: Diff)

Puts a whole difference on this layer, replacing what it held.

pub fn difference(&self, layer: &ModelLayer) -> Option<&Diff>

What this layer holds.

pub fn merged(&self) -> MergedModel

The model, from the bottom up. What finds no node goes to the unusable list, and stays in its difference.

pub fn load( &mut self, layer: &ModelLayer, store: &dyn ModelStore, ) -> Result<(), ModelError>

Reads this layer from a store, if the store has it.

pub fn save( &self, layer: &ModelLayer, store: &dyn ModelStore, ) -> Result<(), ModelError>

Writes this layer to a store.
