Enum Gap 

pub enum Gap {
    Bound,
    Peer,
    Group,
    Section,
    Pane,
    Page,
}

A named separation between two things.

Pick by relationship. The size is a consequence of the name, not the other way round, and callers should never care what it is.

Variants

Bound

A control and the thing it belongs to: an edit field and its pop-up, a checkbox and its label, an icon and the text it labels. Reads as one object.

Peer

Items of the same kind in a list: stacked checkboxes, radio buttons, rows, chips in a row. Reads as a set.

Group

A container’s inner margin, and the distance between sibling groups side by side. Reads as “inside this box”.

Section

Separated groups, and rows of actions. The first gap that reads as a deliberate break rather than as breathing room.

Pane

Panel padding and content shells. Layout, not controls.

Page

The outermost shell margin. One per screen, usually.

Implementations

impl Gap

pub const fn step_at(self, density: Density) -> Step

The step this relationship resolves to at a given density.

pub const fn step(self) -> Step

The step this relationship resolves to at the default density.

pub const fn px_at(self, density: Density) -> u16

Size in CSS pixels at the default base, at a given density.

pub const fn px(self) -> u16

Size in CSS pixels at the default base and density.

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

The CSS custom-property name, without the leading --.

}

pub const fn all() -> [Self; 6]

Every relationship, tightest first.
