Struct bevy_internal::render::settings::InstanceFlags

pub struct InstanceFlags(/* private fields */);

Instance debugging flags.

These are not part of the webgpu standard.

Defaults to enabling debugging-related flags if the build configuration has debug_assertions.

Implementations

impl InstanceFlags

pub const DEBUG: InstanceFlags = _

Generate debug information in shaders and objects.

pub const VALIDATION: InstanceFlags = _

Enable validation, if possible.

pub const DISCARD_HAL_LABELS: InstanceFlags = _

Don’t pass labels to wgpu-hal.

pub const ALLOW_UNDERLYING_NONCOMPLIANT_ADAPTER: InstanceFlags = _

Whether wgpu should expose adapters that run on top of non-compliant adapters.

Turning this on might mean that some of the functionality provided by the wgpu adapter/device is not working or is broken. It could be that all the functionality wgpu currently exposes works but we can’t tell for sure since we have no additional transparency into what is working and what is not on the underlying adapter.

This mainly applies to a Vulkan driver’s compliance version. If the major compliance version is 0, then the driver is ignored. This flag allows that driver to be enabled for testing.

impl InstanceFlags

pub const fn empty() -> InstanceFlags

Get a flags value with all bits unset.

pub const fn all() -> InstanceFlags

Get a flags value with all known bits set.

pub const fn bits(&self) -> u32

Get the underlying bits value.

The returned value is exactly the bits set in this flags value.

pub const fn from_bits(bits: u32) -> Option<InstanceFlags>

Convert from a bits value.

This method will return None if any unknown bits are set.

pub const fn from_bits_truncate(bits: u32) -> InstanceFlags

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u32) -> InstanceFlags

Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<InstanceFlags>

Get a flags value with the bits of a flag with the given name set.

This method will return None if name is empty or doesn’t correspond to any named flag.

pub const fn is_empty(&self) -> bool

Whether all bits in this flags value are unset.

pub const fn is_all(&self) -> bool

Whether all known bits in this flags value are set.

pub const fn intersects(&self, other: InstanceFlags) -> bool

Whether any set bits in a source flags value are also set in a target flags value.

pub const fn contains(&self, other: InstanceFlags) -> bool

Whether all set bits in a source flags value are also set in a target flags value.

pub fn insert(&mut self, other: InstanceFlags)

The bitwise or (|) of the bits in two flags values.

pub fn remove(&mut self, other: InstanceFlags)

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. remove won’t truncate other, but the ! operator will.

pub fn toggle(&mut self, other: InstanceFlags)

The bitwise exclusive-or (^) of the bits in two flags values.

pub fn set(&mut self, other: InstanceFlags, value: bool)

Call insert when value is true or remove when value is false.

pub const fn intersection(self, other: InstanceFlags) -> InstanceFlags

The bitwise and (&) of the bits in two flags values.

pub const fn union(self, other: InstanceFlags) -> InstanceFlags

The bitwise or (|) of the bits in two flags values.

pub const fn difference(self, other: InstanceFlags) -> InstanceFlags

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

pub const fn symmetric_difference(self, other: InstanceFlags) -> InstanceFlags

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> InstanceFlags

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl InstanceFlags

pub const fn iter(&self) -> Iter<InstanceFlags>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<InstanceFlags>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

impl InstanceFlags

pub fn debugging() -> InstanceFlags

Enable debugging and validation flags.

pub fn from_build_config() -> InstanceFlags

Infer good defaults from the build type

Returns the default flags and add debugging flags if the build configuration has debug_assertions.

pub fn with_env(self) -> InstanceFlags

Returns this set of flags, affected by environment variables.

The presence of an environment variable implies that the corresponding flag should be set unless the value is “0” in which case the flag is unset. If the environment variable is not present, then the flag is unaffected.

For example let flags = InstanceFlags::debugging().with_env(); with WGPU_VALIDATION=0 does not contain InstanceFlags::VALIDATION.

The environment variables are named after the flags prefixed with “WGPU_”. For example:

• WGPU_DEBUG
• WGPU_VALIDATION
