Enum Direction 

pub enum Direction {
    Ltr,
    Rtl,
}

The writing direction the layout resolves logical edges against.

Layout is authored in logical terms — start/end rather than left/right — and resolved to physical edges when a style is handed to the engine. One build therefore serves both directions: flipping Direction re-resolves the tree in place instead of rebuilding it, which is why the intent is kept alongside the resolved style rather than baked into it.

Variants

Ltr

Rtl

Implementations

impl Direction

pub fn is_rtl(self) -> bool

pub fn for_locale(locale: &str) -> Direction

The direction conventionally written with locale’s script, keyed by language subtag: Arabic, Hebrew, Persian, Urdu and the other right-to-left languages, matched against the tag’s primary subtag so ar-EG resolves like ar.
