Crate scrin_widgets 

scrin-widgets

scrin-widgets is a plug-and-play Rust widget library for building Scrin-style TUIs with Scrin. It ships animated Aisling effects, ambient glyph fields, glowing gauges, and signal panels that can be dropped into a normal Scrin app.

Install

From this repo:

[dependencies]
scrin-widgets = { path = "." }

Once published to crates.io:

[dependencies]
scrin-widgets = "0.1"

Quick Use

use scrin::{Frame, Rect, widgets::{block::{Block, BorderStyle}, Paragraph, Widget}};
use scrin_widgets::{AislingExt, AislingPalette};

fn draw(frame: &mut Frame<'_>, tick: u64) {
    let area = frame.area();
    let palette = AislingPalette::dream();
    let block = Block::new("Aisling")
        .with_borders(BorderStyle::Plain)
        .with_border_color(palette.pulse)
        .with_inner_margin(Rect::ZERO);
    let inner = block.inner(area);
    let buffer = frame.buffer();

    block.render(buffer, area);
    Paragraph::new("any Scrin widget can shimmer")
        .aisling()
        .tick(tick)
        .render(buffer, inner);
}

Included Widgets

Aisling<W> wraps any Scrin Widget and applies animated shimmer, scanline, and edge-glow effects after the widget renders.

GlyphRain renders a deterministic matrix-like field for backgrounds and data streams.

NebulaGauge renders a glowing progress meter with a flowing fill.

SignalPanel renders a compact status panel with animated signal bars.

FlickerPanel renders text with per-character glitch and flicker effects.

Waveform renders an animated oscilloscope display (sine, square, sawtooth, triangle waves).

PulseRing renders expanding concentric rings from the center of an area.
