Struct ConcealedLine 

pub struct ConcealedLine {
    pub display_text: String,
    pub spans: Vec<StyleSpan>,
    /* private fields */
}

A rendered visual line where concealed syntax tokens have been collapsed, maintaining exact bidirectional mapping to source buffer byte offsets.

Fields

display_text: String

The transformed text to be shaped and rendered on screen.

spans: Vec<StyleSpan>

Syntax highlight spans adjusted to display text coordinates.

Implementations

impl ConcealedLine

pub fn build(line_text: &str, spans: &[StyleSpan]) -> Self

Constructs a concealed line from raw line text and syntax spans.

pub fn expanded(&self, pads: &[DisplayPad]) -> Self

Returns a copy of this line with display-only padding spliced in.

pads are applied in ascending display_at order against the original collapsed coordinates. Span boundaries at or after an insertion point shift right, so inserted padding belongs to the span ending there. Each padding byte maps back to the source offset of the display byte it was inserted before.

pub fn display_to_source(&self, display_col: usize) -> usize

Converts a display byte offset to a source buffer line byte offset.

pub fn source_to_display(&self, source_col: usize) -> usize

Converts a source buffer line byte offset to the nearest display byte offset.

Trait Implementations

impl Clone for ConcealedLine

fn clone(&self) -> ConcealedLine

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConcealedLine

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

Formats the value using the given formatter.
