Struct BlockSnapshot 

pub struct BlockSnapshot {
    pub block_id: usize,
    pub position: usize,
    pub length: usize,
    pub text: String,
    pub fragments: Vec<FragmentContent>,
    pub block_format: BlockFormat,
    pub list_info: Option<ListInfo>,
    pub parent_frame_id: Option<usize>,
    pub table_cell: Option<TableCellContext>,
    pub paint_highlights: Vec<PaintHighlightSpan>,
}

All layout-relevant data for one block, captured atomically.

Fields

block_id: usize

position: usize

length: usize

text: String

fragments: Vec<FragmentContent>

block_format: BlockFormat

list_info: Option<ListInfo>

parent_frame_id: Option<usize>

Parent frame ID. Needed to know where this block lives in the frame tree (e.g. main frame vs. a sub-frame or table cell frame).

table_cell: Option<TableCellContext>

If this block is inside a table cell, the cell coordinates. Needed so the typesetter can propagate height changes to the enclosing table row.

paint_highlights: Vec<PaintHighlightSpan>

Paint-only highlight overlay for this block.

Non-empty only when the active syntax highlighter is paint-only (colors / underline decorations, no metric changes). In that case fragments carry the base formatting (no highlight merge) and the layout engine applies these spans as a post-shape recolor — no reshaping. When a metric-affecting highlighter is active, highlights are merged into fragments as usual and this is empty.

Trait Implementations

impl Clone for BlockSnapshot

fn clone(&self) -> BlockSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockSnapshot

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

Formats the value using the given formatter.

impl PartialEq for BlockSnapshot

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