KAS WGPU

KAS graphics backend over wgpu.

Compiling shaders

This library uses GLSL shaders. Pre-compiled SPIR-V modules are distributed so that users do not need a shader compiler.

For working on GLSL shaders, a compiler such as glslc (part of the shaderc project) is required. glslc can be installed from Fedora packages, but on other platforms manual installation may be required. Alternatively a web-based tool such as glslang.js may be used.

Automatic re-compilation may be enabled by setting e.g. SHADERC=glslc. See build.rs for details.

Optional features

This crate has the following feature flags:

• shaping (enabled by default): use [kas-text]'s default backend (Rustybuzz) for text shaping (alternatively, specify kas-text/harfbuzz or do not use shaping)

By default, this crate uses Swash to raster fonts. This is usually the best choice. As an alternative, fonts can be rastered using ab_glyph; this requires both that the ab_glyph feature is enabled and that the configuration item font.raster.mode is set (see Run-time configuration, RasterConfig::mode).
