Struct SizeHint 

pub struct SizeHint {
    pub min: Size,
    pub preferred: Size,
    pub max: Option<Size>,
}

Size hints for content-aware layout.

Widgets report their sizing requirements through this struct, allowing the layout engine to make intelligent decisions about space allocation.

Fields

min: Size

Minimum size needed to render at all.

preferred: Size

Preferred size for comfortable rendering.

max: Option<Size>

Maximum useful size (content won’t expand beyond).

Implementations

impl SizeHint

pub const fn new(min: Size, preferred: Size, max: Option<Size>) -> Self

Create a new size hint.

pub const fn fixed(size: Size) -> Self

Create a fixed-size hint (all sizes equal).

pub const fn flexible(min: Size) -> Self

Create a flexible hint with only minimum.

Trait Implementations

impl Clone for SizeHint

fn clone(&self) -> SizeHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SizeHint

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

Formats the value using the given formatter.

impl Default for SizeHint

fn default() -> SizeHint

Returns the “default value” for a type.

impl PartialEq for SizeHint

fn eq(&self, other: &SizeHint) -> 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.
