Crate kas

KAS GUI Toolkit

This, the main KAS crate, is a wrapper over other crates designed to make content easily available while remaining configurable. The following crates (some optional, dependant on a feature flag) are re-exported by this crate:

• kas_core is re-export at the top-level
• easy-cast is re-export as kas::cast
• kas_macros is an extended version of impl-tools, re-export at the top-level
• kas_widgets is re-export as kas::widgets
• kas_resvg is re-export as kas::resvg (resvg or tiny-skia feature)
• kas_view is re-export as kas::view (view feature)
• kas_wgpu is re-export as kas::shell; in the current version this is dependant on WGPU, but in the future this should become a shim over multiple back-ends
