Struct StyledTextLayoutParams

pub struct StyledTextLayoutParams<'a> {
    pub text: &'a str,
    pub base_style: TextStyle,
    pub spans: &'a [StyledTextSpan],
    pub max_width: Option<f32>,
    pub wrap_mode: WrapMode,
}

Inputs for styled text layout. Spans affect cache invalidation and prepare the pipeline for syntax-colored runs while preserving a single layout pass.

Overlapping spans are forwarded in slice order to Parley. Every span range must be a valid UTF-8 range in text; callers should not rely on this data structure to clip or repair invalid ranges.

Examples

use ailloli_ui_core::{Color, FontId, TextStyle};
use ailloli_ui_text::{StyledTextLayoutParams, StyledTextSpan, WrapMode};

let base = TextStyle::new(FontId::Mono, 14, Color::WHITE);
let spans = [StyledTextSpan { range: 0..2, style: base.underline() }];
let params = StyledTextLayoutParams {
    text: "fn main",
    base_style: base,
    spans: &spans,
    max_width: Some(120.0),
    wrap_mode: WrapMode::Word,
};
assert_eq!(params.spans.len(), 1);

Fields

text: &'a str

UTF-8 text to shape; an empty string is valid.

base_style: TextStyle

Style used outside overridden ranges.

spans: &'a [StyledTextSpan]

Ordered range overrides, borrowed for the duration of the request.

max_width: Option<f32>

Optional wrap width in logical pixels; None means unconstrained.

wrap_mode: WrapMode

Line-breaking policy.
