Struct ValidationFlags 

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

Available on crate feature unstable-wgpu-26 only.

Validation flags.

If you are working with trusted shaders, then you may be able to save some time by skipping validation.

If you do not perform full validation, invalid shaders may cause Naga to panic. If you do perform full validation and Validator::validate returns Ok, then Naga promises that code generation will either succeed or return an error; it should never panic.

The default value for ValidationFlags is ValidationFlags::all().

Implementations

impl ValidationFlags

pub const fn empty() -> ValidationFlags

Get a flags value with all bits unset.

pub const fn all() -> ValidationFlags

Get a flags value with all known bits set.

pub const fn bits(&self) -> u8

Get the underlying bits value.

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

pub const fn from_bits(bits: u8) -> Option<ValidationFlags>

Convert from a bits value.

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

pub const fn from_bits_truncate(bits: u8) -> ValidationFlags

Convert from a bits value, unsetting any unknown bits.

pub const fn from_bits_retain(bits: u8) -> ValidationFlags

Convert from a bits value exactly.

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

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: ValidationFlags) -> bool

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

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

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

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: ValidationFlags)

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

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

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

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

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

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

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

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

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: ValidationFlags, ) -> ValidationFlags

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

pub const fn complement(self) -> ValidationFlags

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

impl ValidationFlags

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

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<ValidationFlags>

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.
