[features]
default = ["wgsl", "dx12", "metal", "webgpu"]

#! ### Backends
# --------------------------------------------------------------------
#! ⚠️ WIP: Not all backends can be manually configured today.
#! On Windows, Linux & Android the Vulkan & GLES backends are always enabled.
#! See [#3514](https://github.com/gfx-rs/wgpu/issues/3514) for more details.

## Enables the DX12 backend on Windows.
dx12 = ["wgc?/dx12"]

## Enables the Metal backend on macOS & iOS.
metal = ["wgc?/metal"]

## Enables the WebGPU backend on Wasm. Disabled when targeting `emscripten`.
webgpu = ["naga?/wgsl-out"]

## Enables the GLES backend via [ANGLE](https://github.com/google/angle) on macOS using.
angle = ["wgc?/gles"]

## Enables the Vulkan backend on macOS & iOS.
vulkan-portability = ["wgc?/vulkan"]

## Enables the GLES backend on Wasm
##
## * ⚠️ WIP: Currently will also enable GLES dependencies on any other targets.
webgl = ["dep:hal", "wgc/gles"]

#! **Note:** In the documentation, if you see that an item depends on a backend,
#! it means that the item is only available when that backend is enabled _and_ the backend
#! is supported on the current platform.

#! ### Shading language support
# --------------------------------------------------------------------

## Enable accepting SPIR-V shaders as input.
spirv = ["naga/spv-in", "wgc/spirv"]

## Enable accepting GLSL shaders as input.
glsl = ["naga/glsl-in", "wgc/glsl"]

## Enable accepting WGSL shaders as input.
wgsl = ["wgc?/wgsl"]

## Enable accepting naga IR shaders as input.
naga-ir = ["dep:naga"]

#! ### Logging & Tracing
# --------------------------------------------------------------------
#! The following features do not have any effect on the WebGPU backend.

## Apply run-time checks, even in release builds. These are in addition
## to the validation carried out at public APIs in all builds.
strict_asserts = ["wgc?/strict_asserts", "wgt/strict_asserts"]

## Enables serialization via `serde` on common wgpu types.
serde = ["dep:serde", "wgc/serde"]

# Uncomment once we get to https://github.com/gfx-rs/wgpu/issues/5974
# ## Allow writing of trace capture files. See [`Adapter::request_device`].
# trace = ["serde", "wgc/trace"]

## Allow deserializing of trace capture files that were written with the `trace` feature.
## To replay a trace file use the [wgpu player](https://github.com/gfx-rs/wgpu/tree/trunk/player).
replay = ["serde", "wgc/replay"]

#! ### Other
# --------------------------------------------------------------------

## Internally count resources and events for debugging purposes. If the counters
## feature is disabled, the counting infrastructure is removed from the build and
## the exposed counters always return 0.
counters = ["wgc/counters"]

## Implement `Send` and `Sync` on Wasm, but only if atomics are not enabled.
##
## WebGL/WebGPU objects can not be shared between threads.
## However, it can be useful to artificially mark them as `Send` and `Sync`
## anyways to make it easier to write cross-platform code.
## This is technically *very* unsafe in a multithreaded environment,
## but on a wasm binary compiled without atomics we know we are definitely
## not in a multithreaded environment.
