v0.10.0-alpha.1

Toolchain: nightly-2026-04-11 (rustc 1.96.0)

Added ⭐

• PR#493 add spirv-unknown-naga-wgsl target to transpile to wgsl with naga 29

• PR#271 added new targets: vulkan1.3, vulkan1.4, spv1.6

• PR#177 added NonUniform SPIR-V decoration for every image and buffer access when NonUniform capability is enabled

• PR#394 remove unsafe from safe SPIR-V intrinsic functions

• PR#44 added mesh shaders with task shaders and per-primitive output attributes

• entry point:

  • PR#514 allowed zero-sized types in entry point input/output positions
  • PR#509 added validation for incorrect LocalInvocationIndex type, must be u32
  • PR#16 added
    TypedBuffer,
    an explicit way to declare inputs and outputs as buffers, useful for arrays of buffer descriptors
  • PR#448 added arrayed specialization constants, allowing spec constants declared as fixed-size arrays occupying consecutive IDs
  • PR#482 added explicit #[spirv(location = N)] support, fixed overlapping location assignment for larger-than Vec4 structs

• subgroup intrinsics:

  • PR#14 added subgroup intrinsics matching GLSL's GL_KHR_shader_subgroup
  • PR#441 added ScalarComposite trait and derive macro, enabling composite types (scalars, vectors, arrays, structs, repr-int enums) in subgroup intrinsics

• ray tracing:

  • PR#391 added Matrix4x3 type for ray tracing intrinsics
  • PR#343 added RayQuery::get_intersection_triangle_vertex_positions() for ray tracing
  • PR#339 added HitTriangleVertexPositionsKHR built-in for ray tracing pipelines

• spirv-builder

  • PR#477 removed the need for crate-type = ["dylib"] in shader crate Cargo.toml
  • PR#488 replaced enum MetadataPrintout with struct BuildScriptConfig; shader compilation warnings now properly forwarded to build output
  • PR#265 added #[non_exhaustive] on SpirvBuilder and dependent structs; use builder patterns instead of direct construction
  • PR#13 allowed cargo features and default-features to be passed to the shader crate
  • PR#422 redesigned the spirv-builder watch API: simpler Watcher returning CompileResult directly from recv(), with try_recv() for non-blocking polling
  • PR#223 added SpirvBuilder::target_dir_path to set the target directory explicitly
  • PR#188 added RUSTGPU_CARGOFLAGS environment variable for passing extra cargo flags

• cargo-gpu

  • added cargo-gpu to allow CPU code to be compiled by a stable toolchain
  • PR#131 added cargo gpu clippy and cargo gpu check for linting/checking shader code
  • PR#109 added --package/-p akin to cargo
  • PR#16 added [package.metadata.rust-gpu] support in Cargo.toml for declarative build configuration
  • PR#42 added --watch flag for auto-recompilation on source changes
  • PR#71 refactored cargo-gpu from a binary into a library with a public API that's usable from build scripts
  • PR#132 extracted install logic into a separate cargo-gpu-install crate, reducing dependency count by ~30 crates for library consumers

Changed 🛠

• Updated Rust nightly toolchain to nightly-2026-04-11

• PR#249 updated to Rust 2024 edition

• PR#380 glam types have the same layout on GPU and CPU to prevent sutle UB bugs with Vec3, requires at least glam 0.30.8

• PR#395 make many APIs explicitly use glam types instead of generics

• ByteAddressableBuffer:

  • PR#17 refactored ByteAddressableBuffer to allow reading from read-only buffers
  • PR#430 fix ByteAddressableBuffer stores of scalar pair types
  • PR#353 soundness fix: respect read_scalar errors instead of silently corrupting data

• image:

  • PR#281 allow SampledImage to access query_size_lod and query_size
  • PR#361 added Image::fetch_with_lod shortcut for Image::fetch_with(..., lod(...))
  • PR#490 made Image::fetch() implicitly declare LOD 0
  • PR#474 allow Image::write() to write scalar values into scalar images
