Struct Row 

pub struct Row {
    pub runs: Vec<Run>,
    pub decoration: bool,
    pub code: bool,
    pub code_lang: Option<String>,
    pub directive: bool,
    pub directive_label: Option<String>,
    pub heading: Option<u8>,
    pub boundary: Option<Boundary>,
}

One visual line: its styled runs plus the row-level flags a frontend draws chrome from.

Fields

runs: Vec<Run>

decoration: bool

Drawn but holds no caret (a table rule, a block-gap blank line): the renderer skips it for click/caret math. See leaf_core::VRow.

code: bool

A fenced/indented code-block line — the renderer draws a tinted, bordered panel around each maximal run of these.

code_lang: Option<String>

A fenced block’s language, carried on the block’s first code row only.

directive: bool

A :::name{.class} directive-container line — the renderer draws a tinted panel around each maximal run of these, the code recipe. See leaf_core::VRow::directive.

directive_label: Option<String>

A directive container’s space-joined .class attrs, carried on the block’s first row only. See leaf_core::VRow::directive_label.

heading: Option<u8>

The heading level (1–6) if this row belongs to a heading block, else None. A proportional renderer sizes the whole row from this so an inline `code` run inside a heading still reads at the heading’s size.

boundary: Option<Boundary>

What this row divides, on the blank rows a block boundary is drawn with and None everywhere else — so boundary != nil is exactly “this row is a drawn block boundary”. A frontend spaces a boundary by the pair it falls between (the margin above a heading is wider than the one between two paragraphs); the height is the frontend’s, the kind is core’s. See leaf_core::Boundary.
