Struct ParsedLine 

pub struct ParsedLine {
    pub elements: Vec<Element>,
    pub content_vis: Vec<bool>,
    pub image_placeholders: Vec<ImagePlaceholder>,
    /* private fields */
}

Pre-parsed result for a single logical line. Build once per frame via ParsedLine::parse, then reuse across render, cursor, wrap-width, and click-mapping calls to avoid redundant pulldown-cmark invocations.

Fields

elements: Vec<Element>

content_vis: Vec<bool>

Per-char visibility: true = this char is rendered content (not a markdown sigil).

image_placeholders: Vec<ImagePlaceholder>

Image-link spans on this line, sorted by start_char. Their underlying chars are hidden (content_vis = false) and replaced visually by placeholder when rendering.

Implementations

impl ParsedLine

pub fn parse(line: &str) -> Self

Parse a single line in isolation. Internally delegates to ParsedBuffer::parse; kept for test convenience.

When the line looks like an indented list item (e.g. - foo or \t- foo), pulldown-cmark treats it as an indented code block rather than a list item on its own. To preserve the real-editor behaviour (where context from surrounding lines resolves it as a nested list item), prepend a synthetic parent list marker before handing the input to ParsedBuffer::parse and return the result for the original line.

pub fn elem_at(&self, pos: usize) -> Option<usize>

Element index at pos, or None. O(1) via precomputed elem_index.

pub fn in_any_element(&self, pos: usize) -> bool

Whether pos falls inside any tracked element. O(1) via precomputed elem_vis.

pub fn heading_sigil_end(&self) -> Option<usize>

Returns the char offset of the first content char inside a heading element (i.e. the end of the “# “ / “## “ / “### “ sigil region), or None if this line has no heading element.

Defaults to e.end_char so that a heading with no content text (e.g. "#") is fully treated as sigil — fixes the F-02 bug where e.start_char was used.

pub fn list_sigil_end(&self) -> Option<usize>

Char offset where the list-item sigil ends on this line, or None if this line is not the first line of a list item.
