Animation, texture caching, page routing, and a design kit for iced 0.14. Each crate is a normal dependency and does not require an iced fork.
| Crate | Purpose | ||
|---|---|---|---|
iced_animate |
 |
 |
Tree-external animation engine: keyed springs and eases, resolved inside widgets. |
iced_texture_cache |
 |
 |
Render-to-texture caching (Cached, Pager) and the renderer/compositor that make it possible. |
iced_page_router |
 |
 |
Type-erased page router with history, lifecycle, snapshots and a shared-state registry. |
iced_luminate |
 |
 |
The Luminate design kit: theme, descriptors and widgets built on the three crates above. |
Choose the crate that matches your needs:
Use springs and eases without sending a message for every frame:
[dependencies]
iced = "0.14"
iced_animate = "0.1"This crate provides the iced renderer, so views return
iced_texture_cache::Element. It re-exports iced_animate as
iced_texture_cache::iced_animate:
[dependencies]
iced = "0.14"
iced_texture_cache = "0.1"This crate does not depend on the animation or texture crates:
[dependencies]
iced = "0.14"
iced_page_router = "0.1"One dependency re-exports iced and the other three crates:
[dependencies]
iced_luminate = "0.1"All four crates are released together with the same version.
Run with cargo run -p <crate> --example <name>.
| Crate | Example | Shows | Environment |
|---|---|---|---|
iced_animate |
tiers |
paint and layout tiers, keys, sets, springs vs eases, enter/exit | ANIM_AUTOPLAY=1 flips every 1.5 s |
iced_texture_cache |
compositor |
translate/scale/opacity of cached textures, auto-invalidate, nesting | ANIM_AUTOPLAY=1 |
iced_texture_cache |
pager |
Pager sliding between pages of different heights |
ANIM_AUTOPLAY=1 |
iced_texture_cache |
cache_benchmark |
a heavy scene cached vs direct, PixelSnap, FilterQuality, supersampling, the z-order rule (all knobs in-UI) |
BENCH_LOG=1 prints statistics to stderr |
iced_luminate |
overview |
all five descriptors (button hierarchies, an input with its error bubble, a collapsible sidebar, a card, a standalone pager), the theme, the motion tiers, a router with Suspend and Drop pages, a nested router |
none |
ICED_BACKEND=wgpu|tiny-skia forces a backend for any of them;
RUST_LOG=info logs the adapter and surface format (the examples install
env_logger; an application has to install a log backend itself).
nix develop # dev shell with the wgpu/winit system libraries
./ci.sh # fmt, clippy -D warnings, tests, docs, per-crate feature checks, cargo-deny, publish dry-run./ci.sh mirrors the stable, Linux per-crate, deny, and
package jobs of the GitHub workflow, including the multi-package
cargo publish --dry-run. The workflow also runs per-crate on
Linux, macOS and Windows, and cargo-semver-checks
(semver) jobs, and gpu, which repeats the tests on wgpu over Mesa's
software Vulkan driver.
