Struct AbbreviationExpand 

pub struct AbbreviationExpand;

Reads abbreviations from the document frontmatter and wraps the first occurrence of each abbreviation in the document text with an <Abbr> inline component that carries a title attribute containing the expansion.

Frontmatter format

---
abbreviations:
  HTML: HyperText Markup Language
  CSS: Cascading Style Sheets
---

The above will wrap the first occurrence of the literal string "HTML" with <Abbr title="HyperText Markup Language">HTML</Abbr> and similarly for "CSS".

Subsequent occurrences of the same abbreviation are left as plain text.

Notes

• Only Node::Text nodes inside the document body are searched.
• If the frontmatter is absent, or has no abbreviations map, the transform is a no-op.
• Abbreviation matching is case-sensitive and is done on exact sub-string boundaries (the abbreviation must appear as-is in the text).

Trait Implementations

impl Transform for AbbreviationExpand

fn name(&self) -> &str

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

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