Struct nannou_wgpu::DownlevelFlags [−]
pub struct DownlevelFlags { /* fields omitted */ }
Expand description
Binary flags listing features that may or may not be present on downlevel adapters.
A downlevel adapter is a GPU adapter that WGPU supports, but with potentially limited features, due to the lack of hardware feature support.
Flags that are not present for a downlevel adapter or device usually indicates non-compliance with the WebGPU specification, but not always.
You can check whether a set of flags is compliant through the
DownlevelCapabilities::is_webgpu_compliant()
function.
Implementations
impl DownlevelFlags
impl DownlevelFlags
pub const fn compliant() -> DownlevelFlags

All flags that indicate if the backend is WebGPU compliant
impl DownlevelFlags

pub const COMPUTE_SHADERS: DownlevelFlags
pub const COMPUTE_SHADERS: DownlevelFlags
The device supports compiling and using compute shaders.
pub const FRAGMENT_WRITABLE_STORAGE: DownlevelFlags
pub const FRAGMENT_WRITABLE_STORAGE: DownlevelFlags
Supports binding storage buffers and textures to fragment shaders.
pub const INDIRECT_EXECUTION: DownlevelFlags
pub const INDIRECT_EXECUTION: DownlevelFlags
Supports indirect drawing and dispatching.
pub const BASE_VERTEX: DownlevelFlags
pub const BASE_VERTEX: DownlevelFlags
Supports non-zero base_vertex
parameter to indexed draw calls.
pub const READ_ONLY_DEPTH_STENCIL: DownlevelFlags
pub const READ_ONLY_DEPTH_STENCIL: DownlevelFlags
Supports reading from a depth/stencil buffer while using as a read-only depth/stencil attachment.
pub const DEVICE_LOCAL_IMAGE_COPIES: DownlevelFlags
pub const DEVICE_LOCAL_IMAGE_COPIES: DownlevelFlags
Supports:
- copy_image_to_image
- copy_buffer_to_image and copy_image_to_buffer with a buffer without a MAP_* usage
Supports textures with mipmaps which have a non power of two size.
pub const CUBE_ARRAY_TEXTURES: DownlevelFlags
pub const CUBE_ARRAY_TEXTURES: DownlevelFlags
Supports textures that are cube arrays.
pub const COMPARISON_SAMPLERS: DownlevelFlags
pub const COMPARISON_SAMPLERS: DownlevelFlags
Supports comparison samplers.
pub const INDEPENDENT_BLENDING: DownlevelFlags
pub const INDEPENDENT_BLENDING: DownlevelFlags
Supports different blending modes per color target.
pub const VERTEX_STORAGE: DownlevelFlags
pub const VERTEX_STORAGE: DownlevelFlags
Supports storage buffers in vertex shaders.
pub const ANISOTROPIC_FILTERING: DownlevelFlags
pub const ANISOTROPIC_FILTERING: DownlevelFlags
Supports samplers with anisotropic filtering. Note this isn’t actually required by WebGPU, the implementation is allowed to completely ignore aniso clamp. This flag is here for native backends so they can comunicate to the user of aniso is enabled.
pub const FRAGMENT_STORAGE: DownlevelFlags
pub const FRAGMENT_STORAGE: DownlevelFlags
Supports storage buffers in fragment shaders.
pub const fn empty() -> DownlevelFlags
pub const fn empty() -> DownlevelFlags
Returns an empty set of flags.
pub const fn all() -> DownlevelFlags
pub const fn all() -> DownlevelFlags
Returns the set containing all flags.
pub const fn from_bits(bits: u32) -> Option<DownlevelFlags>
pub const fn from_bits(bits: u32) -> Option<DownlevelFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
pub const fn from_bits_truncate(bits: u32) -> DownlevelFlags
pub const fn from_bits_truncate(bits: u32) -> DownlevelFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
pub const unsafe fn from_bits_unchecked(bits: u32) -> DownlevelFlags
pub const unsafe fn from_bits_unchecked(bits: u32) -> DownlevelFlags
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: DownlevelFlags) -> bool
pub const fn intersects(&self, other: DownlevelFlags) -> bool
Returns true
if there are flags common to both self
and other
.
pub const fn contains(&self, other: DownlevelFlags) -> bool
pub const fn contains(&self, other: DownlevelFlags) -> bool
Returns true
if all of the flags in other
are contained within self
.
pub fn insert(&mut self, other: DownlevelFlags)
pub fn insert(&mut self, other: DownlevelFlags)
Inserts the specified flags in-place.
pub fn remove(&mut self, other: DownlevelFlags)
pub fn remove(&mut self, other: DownlevelFlags)
Removes the specified flags in-place.
pub fn toggle(&mut self, other: DownlevelFlags)
pub fn toggle(&mut self, other: DownlevelFlags)
Toggles the specified flags in-place.
pub fn set(&mut self, other: DownlevelFlags, value: bool)
pub fn set(&mut self, other: DownlevelFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
pub const fn intersection(self, other: DownlevelFlags) -> DownlevelFlags
pub const fn intersection(self, other: DownlevelFlags) -> DownlevelFlags
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: DownlevelFlags) -> DownlevelFlags
pub const fn union(self, other: DownlevelFlags) -> DownlevelFlags
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: DownlevelFlags) -> DownlevelFlags
pub const fn difference(self, other: DownlevelFlags) -> DownlevelFlags
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: DownlevelFlags) -> DownlevelFlags
pub const fn symmetric_difference(self, other: DownlevelFlags) -> DownlevelFlags
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) -> DownlevelFlags
pub const fn complement(self) -> DownlevelFlags
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
.
