A discoverable, typo-proof front door for toggling a syntax feature via SyntaxOptions::enable / SyntaxOptions::disable. Each variant maps to one conceptual feature; grouped features flip every underlying Constructs flag together. The raw Constructs struct remains the exhaustive escape hatch for fine-grained control.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Table

GFM pipe tables: | a | b | over |---|---|.

TaskList

GFM task list items: - [ ] / - [x].

Strikethrough

Strikethrough: ~~text~~.

Autolink

GFM literal autolinks plus the cmark relaxed scheme:// extension.

Alert

GFM alerts: > [!NOTE] callouts.

Footnotes

Footnote definitions, references, and inline footnotes.

Math

Inline and block math.

Frontmatter

A leading ---/+++ frontmatter block.

Underline

Underline: __text__ (overrides CommonMark strong).

Insert

Insertions: ++text++.

Highlight

Highlight / mark: ==text==.

Subscript

Subscript: ~text~.

Superscript

Superscript: ^text^.

Spoiler

Spoilers: ||text||.

Shortcode

Emoji-style shortcodes: :tada:.

DescriptionList

Description / definition lists.

Wikilinks(WikiLinkOrder)

Wikilinks [[…]] with the given title order.

MdxJsx

MDX JSX (block and inline). Conflicts with raw HTML; pair with disable-ing HTML or start from SyntaxOptions::mdx.

MdxExpressions

MDX {…} expressions (block and inline).

MdxEsm

MDX ESM import/export lines.

Directives

The :name / ::name / :::name directive family.

Trait Implementations

impl Clone for Construct

fn clone(&self) -> Construct

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Construct

impl Debug for Construct

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Construct

impl PartialEq for Construct

fn eq(&self, other: &Construct) -> bool

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

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
