Struct RichText 

pub struct RichText { /* private fields */ }

Flat rendered rich text with coalesced styled runs and row metadata.

Implementations

impl RichText

pub fn clear(&mut self)

Clears all content while retaining allocated storage.

pub fn rows(&self) -> u16

Returns the number of rendered rows, including a non-empty partial row.

pub fn row_width(&self, row: u16) -> u16

Returns the precomputed terminal-cell width of row.

pub fn row_text(&self, row: u16) -> &str

Returns the plain text in row.

pub fn row_runs( &self, row: u16, ) -> impl DoubleEndedIterator<Item = (Style, &str)> + ExactSizeIterator + Clone + FusedIterator + '_

Iterates the styled runs in row.

pub fn row_soft_wrap(&self, row: u16) -> bool

Whether row soft-wraps onto the following row: it was broken mid-word by width alone, so the pair forms one logical line.

pub fn replay(&self, sink: &mut dyn RichSink)

Replays every row, preserving completed versus trailing partial rows.

pub fn replay_row(&self, row: u16, sink: &mut dyn RichSink)

Replays the runs of one row without appending a newline.

pub fn widest(&self) -> u16

Returns the widest rendered row.

Trait Implementations

impl Clone for RichText

fn clone(&self) -> RichText

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RichText

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

Formats the value using the given formatter.

impl Default for RichText

fn default() -> RichText

Returns the “default value” for a type.

impl RichSink for RichText

fn run(&mut self, style: Style, text: &str)

Appends a styled text run to the current row.

fn newline(&mut self)

Completes the current row and starts another logical row.

fn soft_wrap(&mut self)

Completes the current row at a mid-word soft wrap: the text continues on the next row purely because it hit the layout width, with no whitespace collapsed at the break.
