Backend Adapter Examples

These examples keep backend coverage focused on adapter deltas instead of repeating the full product story.

egui

  • File: examples/10_backend_egui.rs
  • Run:
cargo run --example backend_egui --features egui
  • Expected output: converted egui primitives such as Color32, Frame, cursor, semantic colors, arbitrary colors, and shadow values.

iced

  • File: examples/11_backend_iced.rs
  • Run:
cargo run --example backend_iced --features iced
  • Expected output: converted iced primitives such as Color, Padding, cursor interaction, semantic colors, arbitrary colors, and shadows.

slint

  • File: examples/12_backend_slint.rs
  • Run:
cargo run --example backend_slint --features slint
  • Expected output: converted slint primitives such as slint::Color, lengths, cursor wrapper, semantic colors, arbitrary colors, and shadow tuples.

Why these exist: each adapter example answers “how do I bridge Twill values into this runtime?” without pretending Twill ships a full widget kit.

If you prefer direct adapter dependencies over the facade crate, the matching crates are:

  • twill-egui
  • twill-iced
  • twill-slint
