Struct Panel 

pub struct Panel {
    pub groups: &'static [Group],
    pub exhaustive: bool,
}

One body’s controls, grouped the way its instrument groups them.

⚠️ Not the Electro 5’s CenterPanel and friends, which are bodies — nested #[bitbody]s at a byte range. This is the panel as a reader sees it, and it cuts across those bodies freely.

Fields

groups: &'static [Group]

The sections, in the order a reader meets them.

exhaustive: bool

Whether the groups account for every field the body registers.

True is checked by this module’s tests, so an exhaustive layout stays exhaustive as the body grows: a newly declared field fails the test until it is placed. False means Self::leftovers can be non-empty and a caller needs somewhere to put it.

Implementations

impl Panel

pub fn walk(&self) -> Vec<&Group>

Every group in the layout, sections and their nested clusters alike, depth first.

⚠️ Not groups, which is the top level alone.

pub fn named<'a>(&self, specs: &'a [FieldSpec]) -> Vec<&'a str>

Every path the layout names, in layout order, globs expanded.

pub fn leftovers<'a>(&self, specs: &'a [FieldSpec]) -> Vec<&'a str>

The registered fields no group names, in registry order.

A morph slot whose parameter is named is not among them: it is drawn on that parameter’s control, so a caller that has rendered the parameter has rendered it.

impl Panel

pub fn resolve<'a>(&'a self, fields: &'a [Field]) -> Resolved<'a>

The layout against one body’s field values: every group with its own fields and its effective relevance, plus whatever no group named.

One pass builds an index of the body’s paths, so drawing a layout costs about one walk of the field list however many members the groups name — which matters at the Stage bodies’ scale.

Trait Implementations

impl Debug for Panel

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

Formats the value using the given formatter.
