Enum Dir 

pub enum Dir {
    Ltr,
    Rtl,
    Auto,
}

The dir attribute values for text directionality.

Purpose

Controls the text directionality of an element’s content, which is critical for proper rendering of multilingual content and right-to-left languages.

Usage Context

• Used with: All HTML elements (global attribute)
• Affects: Text rendering direction, visual layout, and text alignment

Valid Values

• Ltr: Left-to-right text direction (default for most languages)
• Rtl: Right-to-left text direction (for languages like Arabic, Hebrew)
• Auto: Browser determines direction based on content

Example

use ironhtml_attributes::{AttributeValue, Dir};
let direction = Dir::Rtl;
assert_eq!(direction.to_attr_value(), "rtl");

<p dir="rtl">مرحبا بك</p>
<p dir="ltr">Hello world</p>

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
