Enum Sizing 

pub enum Sizing {
    Fit,
    Grow(f32),
    Fixed(f32),
    Percent(f32),
    Calc(Calc),
}

How a node sizes one axis. A plain number converts to Fixed, so .width(120.0) and .width(Sizing::Fixed(120.0)) are the same.

Variants

Fit

Size to content.

Grow(f32)

Share leftover space, weighted by factor.

Fixed(f32)

Absolute logical pixels.

Percent(f32)

Fraction of the parent’s content box (0.0..=1.0).

Calc(Calc)

A size expression resolved against the parent’s content box, the box a Percent takes its cut of: "clamp(400px, 80%, 1000px)" (see crate::calc). Layout treats it as it treats a Percent: nothing in the fit pass, its size once the parent’s is known, and a parent that overflows shrinks it as it would one.

Implementations

impl Sizing

pub const GROW: Sizing

Grow(1.0): an equal share of the leftover space, the weight nearly every grow declares.

impl Sizing

pub fn describe(self) -> String

The sizing the way a spec spells it — fit, grow(1), 120px, 50% — for a reader: the devtools’ inspector and a nodes() row.

pub fn amount(self) -> Option<f32>

The animatable number inside: a grow factor, a px size, a fraction. None for Fit and a Calc, which have nothing to ease.

pub fn with_amount(self, v: f32) -> Self

The same form with a different amount (Fit and a Calc stay).

Trait Implementations

impl Clone for Sizing

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Sizing

impl Debug for Sizing

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

Formats the value using the given formatter.

impl Default for Sizing

fn default() -> Self

Returns the “default value” for a type.

impl From<f32> for Sizing

A number is that many logical px, so .width(120.0) is .width(Sizing::Fixed(120.0)), the way min_width(120.0) already read.

fn from(px: f32) -> Self

Converts to this type from the input type.

impl PartialEq for Sizing

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

Equality operator ==.

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

Inequality operator !=.
