Struct StyledText 

pub struct StyledText { /* private fields */ }

A sequence of styled spans representing rich text.

Can be constructed from plain &str / String (unstyled), a single Span, or a Vec<Span>.

Layout concatenates all spans before grapheme segmentation. Splitting a grapheme cluster across spans is supported for width and wrapping, but the cluster uses the style active at its first scalar value.

Implementations

impl StyledText

pub fn new() -> StyledText

Creates an empty styled text sequence.

pub fn push(&mut self, span: Span)

Appends a styled span to this text sequence.

pub fn spans(&self) -> &[Span]

Returns the spans that make up this text sequence.

pub fn spans_mut(&mut self) -> &mut [Span]

Returns mutable access to the spans in this text sequence.

pub fn char_count(&self) -> usize

Total display width in terminal columns.

Wide characters and emoji grapheme clusters count as terminal columns, not Unicode scalar values.

pub fn is_empty(&self) -> bool

Returns true if there is no text content.

pub fn to_cells(&self) -> Vec<Cell>

Converts to a flat sequence of Cells (newlines excluded).
