Struct LineMetrics 

pub struct LineMetrics {
    pub font_size: Pixels,
    pub line_height: Pixels,
    pub is_quote: bool,
    pub is_code_block: bool,
    pub is_thematic_break: bool,
    pub task_state: Option<bool>,
}

Visual layout metrics and block-level decorations for a single rendered line.

Fields

font_size: Pixels

Font size in pixels for this line.

line_height: Pixels

Vertical line height in pixels for this line.

is_quote: bool

Whether this line is a blockquote.

is_code_block: bool

Whether this line is part of a fenced code block.

is_thematic_break: bool

Whether this line is a thematic divider break (—, ***, ___).

task_state: Option<bool>

Whether this line is a task list item (Some(false) for unchecked, Some(true) for checked).

Implementations

impl LineMetrics

pub fn for_line( raw_line_text: &str, _concealed_display_text: &str, spans: &[StyleSpan], base_font_size: Pixels, base_line_height: Pixels, ) -> Self

Calculates layout metrics and block-level decorations based on syntax spans and line text.

spans are the original (pre-concealment) highlight spans for the line. Structural decorations (Blockquote, HorizontalRule, Task*) are detected solely via HighlightTags so custom languages work without raw string checks. Code-block detection relies on a full-line Code span rather than fence prefixes.

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for LineMetrics

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