    pub ParentHandle: Option<String>,
    pub Label: Option<Value>,

    pub CheckboxState: Option<Value>,
}

A serializable struct that represents a vscode.TreeItem.

This DTO is sent from Cocoon (where the TreeDataProvider logic lives) to Mountain (where the UI state is managed) to describe how to render an item in a tree view. It uses serde_json::Value for complex properties to maintain flexibility and compatibility with the VS Code API.

Fields

Handle: String

A unique handle for this item within its tree view, generated by Cocoon.

ParentHandle: Option<String>

The handle of the parent item, if any.

Label: Option<Value>

The label for the tree item. Can be a simple string or a TreeItemLabel object for highlighting.

Description: Option<String>

A human-readable description for the tree item.

ResourceURI: Option<Value>

The URI of the resource represented by this item. Serialized UriComponents.

Tooltip: Option<Value>

The tooltip to show when hovering over the item. Serialized string or IMarkdownStringDTO.

Command: Option<Value>

The command to execute when the item is selected. Serialized CommandDTO.

CollapsibleState: u32

The collapsible state of the item (e.g., None, Collapsed, Expanded). Corresponds to vscode.TreeItemCollapsibleState.

ContextValue: Option<String>

A string that can be used for context-menu visibility (when clauses).

Icon: Option<Value>

A path to an icon or a light/dark pair of paths. Serialized UriComponents.
