Enum LayoutDirection 

pub enum LayoutDirection {
    Ltr,
    Rtl,
}

Reading direction of the application’s layout.

This is a framework-level setting. Individual widgets do not need to be re-authored for RTL — the engine consumes this value at every point where “left” or “right” would otherwise be hardcoded (sidebar side, toast anchor, header end-controls, etc.).

Variants

Ltr

Left-to-right (e.g. English, Japanese, most languages).

Rtl

Right-to-left (e.g. Arabic, Hebrew, Persian).

Implementations

impl LayoutDirection

pub fn flipped(self) -> Self

Flip the direction. Useful for a user-facing “Flip LTR / RTL” toggle during development or accessibility preference changes.

pub fn start_is_left(self) -> bool

Returns true if the logical Edge::Start maps to the physical left side of the screen under this direction.

Useful for engines when they need to decide whether a start-anchored element should be pushed first or last in a horizontal row.

Trait Implementations

impl Clone for LayoutDirection

fn clone(&self) -> LayoutDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LayoutDirection

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

Formats the value using the given formatter.

impl Default for LayoutDirection

fn default() -> LayoutDirection

Returns the “default value” for a type.

impl Hash for LayoutDirection

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LayoutDirection

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