Enum Prominence 

#[non_exhaustive]
pub enum Prominence {
    Lead,
    Support,
    Quiet,
}

How much a part of a row stands out: the row’s default column set.

A part’s content is already a node that says what it is (a badge, a control, a meter), so the part carries only the one thing the node cannot: how far forward it stands in the row. That sets two defaults, the colour it reads in and what it is worth when the run does not fit. A part may say otherwise about its worth, and a renderer reads the part rather than this.

Three steps, and two parts at one step share a column.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Lead

The thing itself: what the row is called. A row that activates is activated through its lead.

Support

What supports the lead: a second line, the row’s badges.

Quiet

A short trailing fact: a count, a size, a date, a proportion.

Implementations

impl Prominence

pub const fn priority(self) -> Priority

What the part is worth when the run does not fit, unless it says.

The lead is Priority::Essential: without it the row does not identify itself. An unknown member reads as Priority::Secondary: droppable, but not first.

pub const fn intent(self) -> &'static str

The content intent text at this step takes.

A part whose node carries its own colour (a badge’s tone, a control, a meter) keeps that colour; this is for the words.
