Struct Span 

pub struct Span<'a> {
    pub text: &'a str,
    pub color: Option<Color>,
    pub bold: bool,
    pub italic: bool,
    pub underline: bool,
    pub underline_color: Option<Color>,
    pub underline_style: UnderlineStyle,
    pub strikethrough: bool,
    pub bg: Option<Color>,
    pub bg_radius: f32,
}

One styled run inside a rich-text paragraph. Spans are shaped and wrapped together as a single flow; plain data, so every frontend can build them.

Fields

text: &'a str

color: Option<Color>

bold: bool

italic: bool

underline: bool

A line under the span, where the face puts its underline.

underline_color: Option<Color>

The underline’s own colour; None is the span’s.

underline_style: UnderlineStyle

The underline’s shape.

strikethrough: bool

A line through the span, where the face puts its strikeout.

bg: Option<Color>

A background behind the span’s glyphs, one rect per line it spans, so it follows the span across a wrap the way a box cannot.

bg_radius: f32

The background’s corner radius, logical px. Above zero, every background of the same colour and radius that meets another edge to edge on the line above or below — in this text or another — is one shape with it: its corners convex where a line reaches past its neighbour, concave where it falls short, round where nothing meets it. What a selection over lines looks like.

Implementations

impl<'a> Span<'a>

pub fn new(text: &'a str) -> Self

pub fn color(self, c: Color) -> Self

pub fn bold(self) -> Self

pub fn italic(self) -> Self

pub fn underline(self) -> Self

pub fn underline_color(self, c: Color) -> Self
