Enum FlexDirection 

pub enum FlexDirection {
    Row,
    Column,
    RowReverse,
    ColumnReverse,
}

Flexbox main-axis direction. Includes the logical *Reverse variants so the layout backend can flip the inline axis when ResolvedDirection is LayoutDirection::Rtl (W5.5).

Variants

Row

Children flow along the inline axis (LTR: left->right).

Column

Children flow along the block axis (top->bottom).

RowReverse

Children flow along the inline axis in reverse (LTR: right->left). W5.5: a plain Row under RTL resolves into this at the layout-backend boundary so authors don’t have to think about mirroring.

ColumnReverse

Children flow along the block axis in reverse (bottom->top).

Implementations

impl FlexDirection

pub const fn resolved(self, dir: LayoutDirection) -> Self

Resolve the logical flex direction under a concrete writing direction. Authors keep writing Row; the backend calls this so Row flips to Self::RowReverse under LayoutDirection::Rtl (mirrors Qt / Web flex semantics). Column / *Reverse pass through unchanged because the block axis is not affected by writing direction.

Trait Implementations

impl Clone for FlexDirection

fn clone(&self) -> FlexDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlexDirection

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

Formats the value using the given formatter.

impl Default for FlexDirection

fn default() -> FlexDirection

Returns the “default value” for a type.

impl PartialEq for FlexDirection

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