Struct bevy::render::options::WgpuFeatures
[−]#[repr(transparent)]pub struct WgpuFeatures { /* private fields */ }
Expand description
Features that are not guaranteed to be supported.
These are either part of the webgpu standard, or are extension features supported by wgpu when targeting native.
If you want to use a feature, you need to first verify that the adapter supports the feature. If the adapter does not support the feature, requesting a device with it enabled will panic.

pub const DEPTH_CLIP_CONTROL: Features
pub const DEPTH_CLIP_CONTROL: Features
By default, polygon depth is clipped to 0-1 range before/during rasterization. Anything outside of that range is rejected, and respective fragments are not touched.
With this extension, we can disabling clipping. That allows shadow map occluders to be rendered into a tighter depth range.
Supported platforms:
- desktops
- some mobile chips
This is a web and native feature.
pub const TEXTURE_COMPRESSION_BC: Features
pub const TEXTURE_COMPRESSION_BC: Features
Enables BCn family of compressed textures. All BCn textures use 4x4 pixel blocks with 8 or 16 bytes per block.
Compressed textures sacrifice some quality in exchange for significantly reduced bandwidth usage.
Support for this feature guarantees availability of [TextureUsages::COPY_SRC | TextureUsages::COPY_DST | TextureUsages::TEXTURE_BINDING
] for BCn formats.
Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES
may enable additional usages.
Supported Platforms:
- desktops
This is a web and native feature.
pub const INDIRECT_FIRST_INSTANCE: Features
pub const INDIRECT_FIRST_INSTANCE: Features
Allows non-zero value for the “first instance” in indirect draw calls.
Supported Platforms:
- Vulkan (mostly)
- DX12
- Metal
This is a web and native feature.
pub const TIMESTAMP_QUERY: Features
pub const TIMESTAMP_QUERY: Features
Enables use of Timestamp Queries. These queries tell the current gpu timestamp when
all work before the query is finished. Call [CommandEncoder::write_timestamp
],
[RenderPassEncoder::write_timestamp
], or [ComputePassEncoder::write_timestamp
] to
write out a timestamp.
They must be resolved using [CommandEncoder::resolve_query_sets
] into a buffer,
then the result must be multiplied by the timestamp period [Device::get_timestamp_period
]
to get the timestamp in nanoseconds. Multiple timestamps can then be diffed to get the
time for operations between them to finish.
Due to wgpu-hal limitations, this is only supported on vulkan for now.
Supported Platforms:
- Vulkan (works)
- DX12 (works)
This is a web and native feature.
pub const PIPELINE_STATISTICS_QUERY: Features
pub const PIPELINE_STATISTICS_QUERY: Features
Enables use of Pipeline Statistics Queries. These queries tell the count of various operations
performed between the start and stop call. Call [RenderPassEncoder::begin_pipeline_statistics_query
] to start
a query, then call [RenderPassEncoder::end_pipeline_statistics_query
] to stop one.
They must be resolved using [CommandEncoder::resolve_query_sets
] into a buffer.
The rules on how these resolve into buffers are detailed in the documentation for [PipelineStatisticsTypes
].
Due to wgpu-hal limitations, this is only supported on vulkan for now.
Supported Platforms:
- Vulkan (works)
- DX12 (works)
This is a web and native feature.
pub const MAPPABLE_PRIMARY_BUFFERS: Features
pub const MAPPABLE_PRIMARY_BUFFERS: Features
Webgpu only allows the MAP_READ and MAP_WRITE buffer usage to be matched with COPY_DST and COPY_SRC respectively. This removes this requirement.
This is only beneficial on systems that share memory between CPU and GPU. If enabled on a system that doesn’t, this can severely hinder performance. Only use if you understand the consequences.
Supported platforms:
- All
This is a native only feature.

] for ETC2 formats.
Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES
may enable additional usages.

] for ASTC formats.
Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES
may enable additional usages.
Supported Platforms:
- Intel/Vulkan
- Mobile (some)
This is a native-only feature.
pub const TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES: Features
pub const TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES: Features
Enables device specific texture format features.
See TextureFormatFeatures
for a listing of the features in question.
By default only texture format properties as defined by the WebGPU specification are allowed. Enabling this feature flag extends the features of each format to the ones supported by the current device. Note that without this flag, read/write storage access is not allowed at all.
This extension does not enable additional formats.
This is a native-only feature.
pub const SHADER_FLOAT64: Features
pub const SHADER_FLOAT64: Features
Enables 64-bit floating point types in SPIR-V shaders.
Note: even when supported by GPU hardware, 64-bit floating point operations are frequently between 16 and 64 times slower than equivalent operations on 32-bit floats.
Supported Platforms:
- Vulkan
This is a native-only feature.
pub const VERTEX_ATTRIBUTE_64BIT: Features
pub const VERTEX_ATTRIBUTE_64BIT: Features

pub const VERTEX_WRITABLE_STORAGE: Features
Enables bindings of writable storage buffers and textures visible to vertex shaders.
Note: some (tiled-based) platforms do not support vertex shaders with any side-effects.
Supported Platforms:
- All
This is a native-only feature.
pub const CLEAR_COMMANDS: Features
pub const CLEAR_COMMANDS: Features
Enables clear to zero for buffers & textures.
Supported platforms:
- All

SPIR-V data is not parsed or interpreted in any way; you can use
[wgpu::make_spirv_raw!
] to check for alignment and magic number when converting from
raw bytes.
Supported platforms:
- Vulkan, in case shader’s requested capabilities and extensions agree with Vulkan implementation.
This is a native only feature.
pub const SHADER_PRIMITIVE_INDEX: Features
pub const SHADER_PRIMITIVE_INDEX: Features
Enables builtin(primitive_index)
in fragment shaders.
Note: enables geometry processing for pipelines using the builtin. This may come with a significant performance impact on some hardware. Other pipelines are not affected.
Supported platforms:

pub const fn from_bits(bits: u64) -> Option<Features>
pub const fn from_bits(bits: u64) -> Option<Features>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u64) -> Features
pub const fn from_bits_truncate(bits: u64) -> Features
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u64) -> Features
pub const unsafe fn from_bits_unchecked(bits: u64) -> Features
Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).
Safety
The caller of the bitflags!
macro can chose to allow or
disallow extra bits for their bitflags type.
The caller of from_bits_unchecked()
has to ensure that
all bits correspond to a defined flag or that extra bits
are valid for this bitflags type.
pub const fn intersects(&self, other: Features) -> bool
pub const fn intersects(&self, other: Features) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: Features) -> bool
pub const fn contains(&self, other: Features) -> bool
Returns true
if all of the flags in other
are contained within self
.
pub fn set(&mut self, other: Features, value: bool)
pub fn set(&mut self, other: Features, value: bool)
Inserts or removes the specified flags depending on the passed value.
pub const fn intersection(self, other: Features) -> Features
pub const fn intersection(self, other: Features) -> Features
Returns the intersection between the flags in self
and
other
.
Specifically, the returned set contains only the flags which are
present in both self
and other
.
This is equivalent to using the &
operator (e.g.
ops::BitAnd
), as in flags & other
.
pub const fn union(self, other: Features) -> Features
pub const fn union(self, other: Features) -> Features
Returns the union of between the flags in self
and other
.
Specifically, the returned set contains all flags which are
present in either self
or other
, including any which are
present in both (see Self::symmetric_difference
if that
is undesirable).
This is equivalent to using the |
operator (e.g.
ops::BitOr
), as in flags | other
.
pub const fn difference(self, other: Features) -> Features
pub const fn difference(self, other: Features) -> Features
Returns the difference between the flags in self
and other
.
Specifically, the returned set contains all flags present in
self
, except for the ones present in other
.
It is also conceptually equivalent to the “bit-clear” operation:
flags & !other
(and this syntax is also supported).
This is equivalent to using the -
operator (e.g.
ops::Sub
), as in flags - other
.
pub const fn symmetric_difference(self, other: Features) -> Features
pub const fn symmetric_difference(self, other: Features) -> Features
Returns the symmetric difference between the flags
in self
and other
.
Specifically, the returned set contains the flags present which
are present in self
or other
, but that are not present in
both. Equivalently, it contains the flags present in exactly
one of the sets self
and other
.
This is equivalent to using the ^
operator (e.g.
ops::BitXor
), as in flags ^ other
.
pub const fn complement(self) -> Features
pub const fn complement(self) -> Features
Returns the complement of this set of flags.
Specifically, the returned set contains all the flags which are
not set in self
, but which are allowed for this type.
Alternatively, it can be thought of as the set difference
between Self::all()
and self
(e.g. Self::all() - self
)
This is equivalent to using the !
operator (e.g.
ops::Not
), as in !flags
.
