The full set of syntactic constructs the parser may recognize, one boolean per feature. This is the exhaustive escape hatch; most callers use the Constructs::commonmark/gfm/mdx/ max presets or the Construct builder instead of setting fields directly.

Fields

html_block: bool

Raw HTML blocks, e.g. a <div>…</div> block at the top level.

html_inline: bool

Raw inline HTML, e.g. <span> within a paragraph.

indented_code: bool

Indented code blocks (each line indented four spaces or a tab).

gfm_table: bool

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

gfm_task_list_item: bool

GFM task list items: - [ ] (unchecked) and - [x] (checked).

gfm_strikethrough: bool

GFM strikethrough: ~~text~~.

gfm_autolink_literal: bool

GFM literal autolinks: a bare https://…, www.…, or email becomes a link without angle brackets.

relaxed_autolinks: bool

cmark-gfm “relaxed” URL autolinks: bare scheme:// URLs (and a bare leading ://) are auto-linkified without angle brackets, e.g. smb://, irc://, rdar://. This is a cmark extension beyond the GFM spec (which defines only http(s):///www./email); on by default in gfm() for GitHub/cmark-gfm parity. The angle form <scheme:…> works regardless.

gfm_alert: bool

GFM alerts: a > [!NOTE] (TIP/IMPORTANT/WARNING/CAUTION) blockquote.

underline: bool

Underline spans: __text__. This overrides CommonMark’s __-as-strong, so it is off in the max default.

insert: bool

CriticMarkup-style insertions: ++text++.

highlight: bool

Highlight / “mark” spans: ==text==.

subscript: bool

Subscript: a single-tilde span ~text~ (no spaces).

superscript: bool

Superscript: ^text^.

spoiler: bool

Spoiler spans: ||text||.

shortcode: bool

Emoji-style shortcodes: :tada:.

description_list: bool

Description (definition) lists: a term followed by :-led details.

footnote_definition: bool

Footnote definitions: [^1]: the footnote body.

footnote_reference: bool

Footnote references: [^1] in running text.

inline_footnote: bool

Inline footnotes: ^[the note inline] (also needs footnote_reference).

math_block: bool

Block math: a $$ … $$ fenced block.

math_inline: bool

Inline math: $x$ (and the math-code form $`x`$).

frontmatter: bool

A leading frontmatter block at the start of the document: --- YAML or +++ TOML.

wikilink_title_after_pipe: bool

Wikilinks with the display title after the pipe: [[target|title]] (the Obsidian convention). Mutually exclusive with the before-pipe order.

wikilink_title_before_pipe: bool

Wikilinks with the display title before the pipe: [[title|target]]. Mutually exclusive with the after-pipe order.

mdx_esm: bool

MDX ESM: import/export statement lines.

mdx_expression_block: bool

MDX block-level { … } expressions.

mdx_expression_inline: bool

MDX inline { … } expressions within text.

mdx_jsx_block: bool

MDX block-level JSX: <Component/> as a block. Conflicts with raw HTML.

mdx_jsx_inline: bool

MDX inline JSX: <Component/> within text. Conflicts with raw HTML.

directive_text: bool

Inline directive: :name[label]{key=val}. A directive, not MDX.

directive_leaf: bool

Leaf directive: ::name[label]{key=val} on its own line. A directive, not MDX.

directive_container: bool

Container directive: a :::name … ::: fenced block. A directive, not MDX.

Implementations

impl Constructs

pub const fn commonmark() -> Self

The CommonMark baseline: raw HTML and indented code, no extensions.

pub const fn gfm() -> Self

GitHub Flavored Markdown: CommonMark plus tables, task lists, strikethrough, literal autolinks, and footnotes.

pub const fn mdx() -> Self

MDX: CommonMark with raw HTML and indented code off, and MDX ESM, expressions, and JSX on.

pub const fn max() -> Self

The maximal non-MDX construct set, and the default dialect: every construct that does not reinterpret a core CommonMark delimiter. MDX is off (it conflicts with raw HTML and reinterprets {…}/<…>), and underline is off because it would parse __bold__ as underline, overriding CommonMark strong. The wikilink title order is after-pipe.

Trait Implementations

impl Clone for Constructs

fn clone(&self) -> Constructs

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constructs

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

Formats the value using the given formatter.

impl Default for Constructs

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Constructs

impl PartialEq for Constructs

fn eq(&self, other: &Constructs) -> 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.
