BlockMeta

Struct BlockMeta 

Source
pub struct BlockMeta {
    pub source_line: Option<usize>,
}
Expand description

Per-top-level-block metadata.

Holds parse-time annotations that don’t belong on the Block enum itself (which is shape-only). Lives in a parallel Vec<BlockMeta> on Document so existing pattern matches over Block don’t need to unwrap a meta wrapper.

Today the only field is source_line (set by the parser when crate::ast::ParseConfig::emit_source_lines is true). Additional per-block annotations (block IDs, custom attrs, etc.) land here too when needed.

Fields§

§source_line: Option<usize>

1-based source line where this block begins, or None when source tracking is off (or the block was synthesized — e.g. shortcode substitution — and has no faithful source position).

Consumed by the renderer to emit data-source-line="N" on the opening tag, which the preview’s cm-scroll-sync consumes for paragraph-level editor↔preview scroll sync.
