Expand description

A classified HTML tag name.

Known elements (the HTML5 set plus the foreign-content and legacy tags the parser tracks) are fieldless variants; anything else is Other, borrowing the original-case name bytes.

Variants (Non-exhaustive)§

This enum is marked as 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.

Implementations§

§

impl<'a> HtmlTag<'a>

pub fn as_bytes(&self) -> &'a [u8] ⓘ

The tag name as bytes — lowercase for a known element, the original bytes for Other.

§

impl HtmlTag<'_>

pub fn is_void(&self) -> bool

Returns true if this is an HTML5 void element: one that never has content or an end tag — area, base, br, col, embed, hr, img, input, link, meta, source, track, wbr.

Note param is not void in the current spec (it is obsolete).

pub fn is_raw_text(&self) -> bool

Returns true if this is a raw text element — script or style. Their content is tokenized verbatim: no markup, no character references, only the matching end tag closes them.

This is the spec category, not rama’s broader tokenizer raw-text set (which also covers legacy xmp / iframe / noembed / noframes / noscript).

pub fn is_escapable_raw_text(&self) -> bool

Returns true if this is an escapable raw text element — textarea or title. Like a raw text element, but character references are recognized in its content.

pub fn is_phrasing_content(&self) -> bool

Returns true if this is phrasing content — the spec category for the text-level (“inline”) elements: the runs of text in a document and the elements that mark them up (a, span, em, strong, img, br, input, script, …).

Membership is the current WHATWG list of elements that are inherently phrasing content. Elements that qualify only in a specific context (area within a map, link / meta carrying an itemprop) are excluded — this is a name-only predicate. Obsolete presentational tags (big, font, tt, strike, nobr) are excluded too; they are not in the modern content model.
