Struct PrintFallback 

pub struct PrintFallback;

When producing print output, replaces components that carry a printFallback attribute with a simpler representation.

• If the fallback value looks like an image path (ends with .png, .jpg, .jpeg, .gif, .svg, or .webp) the component is replaced with a Node::Image.
• Otherwise the component is replaced with a Node::Text containing the fallback string.

Components without a printFallback attribute are left unchanged.

The transform itself is stateless — the caller is responsible for applying it only when targeting print output.

Example

use rdx_transform::{PrintFallback, Transform, parse};

let mut root = parse(
    "<InteractiveChart printFallback=\"chart.png\" />\n",
);
PrintFallback.transform(&mut root, "");
// The component is now an Image node pointing to "chart.png".
assert!(matches!(root.children[0], rdx_transform::Node::Image(_)));

Trait Implementations

impl Transform for PrintFallback

fn name(&self) -> &str

A short identifier for this transform (used in error messages / debugging).

fn transform(&self, root: &mut Root, _source: &str)

Apply the transform to the AST. source is the original document text, available for transforms that need to reference raw content.
