Struct Model 

pub struct Model {
    pub nodes: Vec<Node>,
    pub roots: Vec<usize>,
    pub pass: u64,
}

The element tree of one frame.

Fields

nodes: Vec<Node>

roots: Vec<usize>

pass: u64

egui pass it was built from.

Implementations

impl Model

pub fn build(src: &Sources<'_>, refs: &mut Refs) -> Model

Build the tree; refs keeps refs stable across builds.

pub fn get(&self, i: usize) -> Option<&Node>

pub fn preorder(&self, scope: Option<usize>) -> Vec<usize>

Nodes in reading order (pre-order), starting at scope or the roots.

pub fn by_key(&self, key: u64) -> Option<usize>

pub fn at(&self, p: Pos2) -> Option<usize>

The smallest visible element under p.

pub fn shows_text(&self, text: &str) -> bool

Whether any visible element shows text (in its name or value).

pub fn outline(&self, opts: &Outline) -> (String, Vec<usize>)

The text outline (- button "Save" [ref=e3]) and the nodes it lists.

impl Model

pub fn resolve( &self, t: &Target, refs: &Refs, generation: u64, ) -> Result<Hit, Miss>

Find t in this model. generation is the latest snapshot’s, for the stale-ref error.

pub fn find_text(&self, text: &str, role: Option<&str>) -> Option<usize>

The first visible element named text: exact, then ignoring case, then containing it; interactive ones first within each tier.

Trait Implementations

impl Debug for Model

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

Formats the value using the given formatter.

impl Default for Model

fn default() -> Self

Returns the “default value” for a type.
