Struct ModelNode 

pub struct ModelNode {
    pub id: String,
    pub properties: BTreeMap<String, Value>,
    pub children: Vec<ModelNode>,
}

A node of the application model: an id, settings and nodes under it.

Fields

id: String

What it is known by among the nodes beside it.

properties: BTreeMap<String, Value>

Its settings.

children: Vec<ModelNode>

The nodes under it, in the order they came.

Implementations

impl ModelNode

pub fn new(id: impl Into<String>) -> Self

A node with no settings and nothing under it.

pub fn with(self, name: &str, value: impl Into<Json>) -> Self

With this setting.

pub fn child(self, child: ModelNode) -> Self

With this node under it.

pub fn get(&self, id: &str) -> Option<&ModelNode>

The node under it with this id.

pub fn at(&self, path: &[&str]) -> Option<&ModelNode>

The node at this path of ids below it.

pub fn text(&self, name: &str) -> Option<&str>

A setting as text.

pub fn typed(&self, name: &str) -> Option<String>

A setting as it is typed: text as it is, and anything else as JSON.

pub fn integer(&self, name: &str) -> Option<i64>

A setting as a whole number.

pub fn number(&self, name: &str) -> Option<f64>

A setting as a number.

pub fn flag(&self, name: &str) -> Option<bool>

A setting as yes or no.

pub fn in_order(&self) -> Vec<&ModelNode>

The nodes under it in the order to show them: by Index, then as they came. A negative index keeps a node out of sight, so it is not here.
