Shared data structures
This crate includes common geometry representations, tiling logic, and other fundamental components used by both Vello CPU and Vello Hybrid.
This crate should not be used on its own, and you should instead use one of the renderers which use it. At the moment, only Vello CPU is published, and you probably want to use that.
We also develop Vello, which makes use of the GPU for 2D rendering and has higher performance than Vello CPU. Vello CPU is being developed as part of work to address shortcomings in Vello. Vello does not use this crate.
std (enabled by default): Get floating point functions from the standard library (likely using your target's libc).libm: Use floating point implementations from libm.png (enabled by default): Allow loading Pixmaps from PNG images. Also required for rendering glyphs with an embedded PNG. Implies std.simd: Allows requesting SIMD execution modes. Note that SIMD is not yet implemented.At least one of std and libm is required; std overrides libm.
This crate acts as a foundation for vello_cpu and vello_hybrid, providing essential components to minimize duplication.
This version of Vello Common has been verified to compile with Rust 1.85 and later.
Future versions of Vello Common might increase the Rust version requirement. It will not be treated as a breaking change and as such can even happen with small patch releases.
As time has passed, some of Vello Common‘s dependencies could have released versions with a higher Rust requirement. If you encounter a compilation issue due to a dependency and don’t want to upgrade your Rust toolchain, then you could downgrade the dependency.
# Use the problematic dependency's name and version cargo update -p package_name --precise 0.1.1
