KAS GUI

KAS is a stateful, pure-Rust GUI toolkit supporting:

• Mostly declarative UI descriptions
• Stateful widgets (e.g. selection range or a pure-UI counter)
• Virtual scrolling (list or matrix), including support for external data sources
• Theme abstraction including theme-driven animations and sizing
• Multiple renderer backends
• Integrated i18n support
• Accessibility tool integration
• Platform integration: persistent configuration, theme discovery, external menus, IME
• Most of the basics you'd expect: complex text, fractional scaling, automatic margins
• Extremely fast, monolithic binaries

Crates and features

kas is a meta-package serving as the library's public API, but containing no real code. Other crates in this repo:

• kas-core: the core library
• kas-widgets: the main widget library
• kas-view: view widgets supporting virtual scrolling
• kas-resvg: extra widgets over resvg
• kas-dylib: helper crate to support dynamic linking
• kas-macros: proc-macro crate

Significant external dependencies:

• kas-text: complex text support
• impl-tools: autoimpl and impl_scope (extensible) macros
• winit: platform window integration
• wgpu: modern accelerated graphics API

Feature flags

The kas crate enables most important features by default, excepting those requiring nightly rustc. Other crates enable fewer features by default. See Cargo.toml.

Size

To reduce binary size, add this to your Cargo.toml:

[profile.release]
strip = true
opt-level = "z"

You might also consider using feature dynamic if wishing to ship multiple binaries with shared libraries (Rust's libstd and libkas_dylib); note however that these are not ABI-stable.
