Struct EditorModel 

pub struct EditorModel {
    pub recipe_name: String,
    pub recipe_description: String,
    pub nodes: Vec<EditorNode>,
    pub selected_index: Option<usize>,
    pub dirty: bool,
    pub undo_stack: Vec<EditorSnapshot>,
    pub redo_stack: Vec<EditorSnapshot>,
    pub source: EditorSource,
}

The main editor state. Pure data — all mutations are method calls that modify fields in place. No I/O, no side effects.

Fields

recipe_name: String

recipe_description: String

nodes: Vec<EditorNode>

selected_index: Option<usize>

dirty: bool

undo_stack: Vec<EditorSnapshot>

redo_stack: Vec<EditorSnapshot>

source: EditorSource

Implementations

impl EditorModel

pub fn from_definition(def: &Definition, source: EditorSource) -> Self

Build an editor model from a parsed Definition.

pub fn to_definition(&self) -> Definition

Serialize the editor state back to a Definition.

impl EditorModel

pub fn load(path: &Path) -> Result<Self, EditorError>

Load a recipe from a .bnto.json file.

pub fn save_to(&self, path: &Path) -> Result<(), EditorError>

Save the current editor state to a .bnto.json file. Uses atomic write (write to temp, then rename) to prevent corruption.

pub fn save_path(&self, recipes_dir: &Path) -> PathBuf

Resolve the save destination path based on the recipe’s source.

• File(path) → save back to that path
• New or Predefined → save to recipes_dir/{slug}.bnto.json

impl EditorModel

pub fn add_node(&mut self, node_type: &str, info: &NodeTypeInfo)

Add a node with defaults populated from engine metadata.

pub fn add_node_with_defaults( &mut self, node_type: &str, info: &NodeTypeInfo, param_defaults: &[(String, Value)], )

Add a node with pre-populated default parameter values from metadata.

pub fn remove_node(&mut self, index: usize)

Remove the node at the given index.

pub fn reorder(&mut self, from: usize, to: usize)

Swap nodes at positions from and to.

pub fn update_param(&mut self, index: usize, key: &str, value: Value)

Update a single parameter value on the node at index.

pub fn undo(&mut self)

Undo the last mutation.

pub fn redo(&mut self)

Redo the last undone mutation.

pub fn mark_clean(&mut self)

Mark the model as clean (after a successful save).

impl EditorModel

pub fn new() -> Self

Create a blank editor with no nodes.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for EditorModel

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

Formats the value using the given formatter.

impl Default for EditorModel

fn default() -> Self

Returns the “default value” for a type.
