Usage and composition

Import

use maud_ui::primitives::progress::{self, Props};

Example

use maud::html;
use maud_ui::primitives::progress;

html! {
    (progress::render(progress::Props {
        value: 65,
        max: 100,
        label: "Uploading file, 65 percent".into(),
        indeterminate: false,
    }))
}

Variants

Determinate

Concrete progress: bar fills proportionally to value / max.

(progress::render(progress::Props {
    value: 40,
    max: 100,
    label: "Sync status, 40 percent".into(),
    indeterminate: false,
}))

Indeterminate

Animated bar for unknown duration (e.g., "processing...").

(progress::render(progress::Props {
    indeterminate: true,
    label: "Processing request".into(),
    ..Default::default()
}))

Helpers

label(text: &str) -> Markup

Renders a <span class="mui-progress__label"> for semantic label text. Matches shadcn ProgressLabel.

(progress::label("Download progress"))

value(val: u32) -> Markup

Renders a <span class="mui-progress__value"> displaying "{val}%". Matches shadcn ProgressValue.

(progress::value(75))  // Output: "75%"

Usage Pattern

Combine label, value, and render in a flex layout:

html! {
    div style="display:flex;justify-content:space-between;align-items:center;margin-bottom:0.5rem" {
        (progress::label("Sync status"))
        (progress::value(40))
    }
    (progress::render(progress::Props {
        value: 40,
        max: 100,
        label: "Sync status, 40 percent".into(),
        indeterminate: false,
    }))
}

  • Determinate: aria-valuenow, aria-valuemin="0", aria-valuemax="{max}", aria-label="{label}".
  • Indeterminate: aria-valuemin="0", aria-valuemax="{max}", aria-label="{label}" (no valuenow).
  • Label must be descriptive for screen readers (e.g., "Uploading file, 65 percent").
