Struct Constraints 

pub struct Constraints {
    pub max_width: f32,
    pub max_height: f32,
}

Restricciones de tamaño que un LayoutBuilderFn recibe: las dimensiones del slot que el layout le asignó al nodo (en px físicos). Análogo a las BoxConstraints de Flutter LayoutBuilder / al MediaQuery pero local al nodo (no a la ventana). El builder construye su subárbol en función de esto — p. ej. una columna si max_width < 600, dos si es ancho.

Fields

max_width: f32

max_height: f32

Trait Implementations

impl Clone for Constraints

fn clone(&self) -> Constraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Constraints

impl Debug for Constraints

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

Formats the value using the given formatter.

impl PartialEq for Constraints

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