Enum LineKind 

pub enum LineKind {
    Para,
    Heading {
        level: u8,
    },
    Code {
        lang: Option<String>,
    },
    Island,
    Rule,
}

The block role of a line. The tree between lines is inferred: two adjacent lines with equal kind+containers are two blocks of that role (e.g. two paragraphs), never one.

Closed, on the same terms as MarkKind: a kind outside this set is ParseError::UnknownName at every decoder, so adding a role is a storage-version event.

Variants

Para

Heading

ATX/Setext heading, level 1..=6.

Fields

level: u8

Code

A line of a code block. lang is the (sanitized) info string, shared by every line of the same block.

Fields

lang: Option<String>

Island

A block-level island: the line’s sole content is one ISLAND_SLOT backing an island whose markdown is a block (IslandType::block_only). An image is inline markup, so a line holding one alone is Para — the kind re-importing ![alt](url) yields, and the kind Content::normalize writes there.

Rule

A thematic break (---/***/___). The line carries no text.

Implementations

impl LineKind

pub fn takes_continuations(&self) -> bool

Whether a block of this kind renders the lines that Line::continues joins to its first. A paragraph spans its hard-break run and a code block its fence’s interior; a heading, an island and a rule are one line, and both emitters render that line alone, so a continuation there is text the projection never reaches.

pub fn tag(&self) -> &'static str

The wire kind name.

pub fn attrs(&self) -> Cow<'_, JsonValue>

The payload bag, one spelling for every member of the vocabulary.
