Struct CrossRefResolve 

pub struct CrossRefResolve {
    pub registry: NumberRegistry,
    pub target: String,
}

Resolves Node::CrossRef nodes by looking up their target label in a NumberRegistry produced by crate::AutoNumber.

For the “web” target a CrossRef is replaced by a Node::Link whose url is #<target> and whose display text is e.g. "Figure 1".

For the “print” target the node is replaced by a plain Node::Text containing the same display text (page numbers would be added by a downstream typesetter).

If the target label is not found in the registry the CrossRef node is left in place unchanged so that downstream tools can handle it or report the error.

Example

use rdx_transform::{AutoNumber, CrossRefResolve, Transform, parse};

let mut root = parse(
    "<Figure id=\"fig:arch\">\n</Figure>\n\
     See {@fig:arch}.\n",
);
let numberer = AutoNumber::new();
numberer.transform(&mut root, "");
let registry = numberer.registry().entries.clone();
let resolver = CrossRefResolve::new(
    rdx_transform::NumberRegistry { entries: registry },
    "web",
);
resolver.transform(&mut root, "");

Fields

registry: NumberRegistry

target: String

Output target: "web" or "print".

Implementations

impl CrossRefResolve

pub fn new(registry: NumberRegistry, target: impl Into<String>) -> Self

Trait Implementations

impl Transform for CrossRefResolve

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.
