Struct Span 

#[non_exhaustive]
pub struct Span {
    pub range: Range<usize>,
    pub color: Option<Color>,
    pub size_px: Option<f32>,
}

A styled part of a paragraph’s text.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

range: Range<usize>

Byte range of the text it styles; must lie on character boundaries.

color: Option<Color>

Text color, if different from the paragraph’s.

size_px: Option<f32>

Font size in pixels per em, if different from the paragraph’s.

Implementations

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

The span coloring its text color.

pub fn with_size(self, size_px: f32) -> Self

The span setting its text at size_px pixels per em.
