Struct wgpu::DownlevelFlags [−][src]
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
All flags that indicate if the backend is WebGPU compliant
The device supports compiling and using compute shaders.
Supports binding storage buffers and textures to fragment shaders.
Supports indirect drawing and dispatching.
Supports non-zero base_vertex
parameter to indexed draw calls.
Supports reading from a depth/stencil buffer while using as a read-only depth/stencil attachment.
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.
Supports textures that are cube arrays.
Supports comparison samplers.
Supports different blending modes per color target.
Supports storage buffers in vertex shaders.
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.
Supports storage buffers in fragment shaders.
Returns an empty set of flags.
Returns the set containing all flags.
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
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.
Returns true
if there are flags common to both self
and other
.
Returns true
if all of the flags in other
are contained within self
.
Inserts the specified flags in-place.
Removes the specified flags in-place.
Toggles the specified flags in-place.
Inserts or removes the specified flags depending on the passed value.
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
.
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
.
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
.
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
.
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
.
