Struct HeaderRowMetrics 

pub struct HeaderRowMetrics {
    pub height: f64,
    pub chip: f64,
    pub inset: f64,
    pub gap: f64,
    pub gutter: f64,
}

The header row’s sizes, resolved against one theme.

Fields

height: f64

Height of the row: metrics.header_height, never less than a shell button in its inset.

chip: f64

Side of a shell button (min_pointer_target, grown with the text).

inset: f64

Inset of the shell buttons from the row’s edges (s3).

gap: f64

Gap between neighbours in the row (s2).

gutter: f64

Inset of a title with no leading button: the content gutter (rhythm.group), so the title lines up with the content under it.

Implementations

impl HeaderRowMetrics

pub fn resolve(theme: &Theme) -> HeaderRowMetrics

The row for a fine pointer. A window that knows its input resolves it with Self::resolve_for.

pub fn resolve_for( theme: &Theme, input: InteractionEnvironment, ) -> HeaderRowMetrics

The row for a person using input: a shell button is a square of the minimum target input needs, as an app’s buttons are (a coarse pointer grows the face to it; a fine one keeps min_pointer_target and reaches the target through its hit rect). The row keeps its height while the grown square fits it with s1 above and below, so touch moves nothing under the row.

pub fn leading_chip(&self, row: Rect, index: usize) -> Rect

A shell button’s square, index places from the leading edge of row (0 is the corner).

pub fn trailing_chip(&self, row: Rect, index: usize) -> Rect

A shell button’s square, index places from the trailing edge of row (0 is the corner).

pub fn trailing_chip_from(&self, row: Rect, index: usize, edge: f64) -> Rect

Self::trailing_chip measured edge in from the row’s trailing end: the content gutter where the row’s controls keep the gutter its title starts at, the inset beside a sidebar.

Trait Implementations

impl Clone for HeaderRowMetrics

fn clone(&self) -> HeaderRowMetrics

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeaderRowMetrics

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

Formats the value using the given formatter.

impl Default for HeaderRowMetrics

fn default() -> HeaderRowMetrics

Returns the “default value” for a type.

impl PartialEq for HeaderRowMetrics

fn eq(&self, other: &HeaderRowMetrics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
