Enum FlowDirection 

pub enum FlowDirection {
    Horizontal,
    Vertical,
}

Text flow direction for a rendering run.

Governs how the layout engine advances the cursor between glyphs and lines. Horizontal is the default (left-to-right or bidi-resolved RTL within lines). Vertical enables top-to-bottom CJK flow as per UAX #50.

Variants

Horizontal

Standard horizontal text (LTR/RTL decided by bidi algorithm).

Vertical

Vertical text, advancing top-to-bottom (used for CJK vertical layout).

Trait Implementations

impl Clone for FlowDirection

fn clone(&self) -> FlowDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FlowDirection

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

Formats the value using the given formatter.

impl Default for FlowDirection

fn default() -> FlowDirection

Returns the “default value” for a type.

impl Hash for FlowDirection

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 FlowDirection

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