Struct wgpu::naga::valid::TypeFlags

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

Flags associated with Types by Validator.

Implementations

impl TypeFlags

pub const DATA: TypeFlags = _

Can be used for data variables.

This flag is required on types of local variables, function arguments, array elements, and struct members.

This includes all types except Image, Sampler, and some Pointer types.

pub const SIZED: TypeFlags = _

The data type has a size known by pipeline creation time.

Unsized types are quite restricted. The only unsized types permitted by Naga, other than the non-DATA types like Image and Sampler, are dynamically-sized [Arrays], and [Structs] whose last members are such arrays. See the documentation for those types for details.

pub const COPY: TypeFlags = _

The data can be copied around.

pub const IO_SHAREABLE: TypeFlags = _

Can be be used for user-defined IO between pipeline stages.

This covers anything that can be in [Location] binding: non-bool scalars and vectors, matrices, and structs and arrays containing only interface types.

pub const HOST_SHAREABLE: TypeFlags = _

Can be used for host-shareable structures.

pub const ARGUMENT: TypeFlags = _

This type can be passed as a function argument.

pub const CONSTRUCTIBLE: TypeFlags = _

A WGSL constructible type.

The constructible types are scalars, vectors, matrices, fixed-size arrays of constructible types, and structs whose members are all constructible.

impl TypeFlags

pub const fn empty() -> TypeFlags

Get a flags value with all bits unset.

pub const fn all() -> TypeFlags

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<TypeFlags>

Convert from a bits value.

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

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

Convert from a bits value, unsetting any unknown bits.

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

Convert from a bits value exactly.

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

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: TypeFlags) -> bool

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

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

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

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

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

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

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: TypeFlags)

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

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

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

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

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

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

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

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

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: TypeFlags) -> TypeFlags

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

pub const fn complement(self) -> TypeFlags

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

impl TypeFlags

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

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<TypeFlags>

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.
