Struct wgpu_hal::TextureUses

pub struct TextureUses { /* private fields */ }

Similar to wgt::TextureUsages but for internal use.

Implementations

impl TextureUses

pub const UNINITIALIZED: Self = _

The texture is in unknown state.

pub const PRESENT: Self = _

Ready to present image to the surface.

pub const COPY_SRC: Self = _

The source of a hardware copy.

pub const COPY_DST: Self = _

The destination of a hardware copy.

pub const RESOURCE: Self = _

Read-only sampled or fetched resource.

pub const COLOR_TARGET: Self = _

The color target of a renderpass.

pub const DEPTH_STENCIL_READ: Self = _

Read-only depth stencil usage.

pub const DEPTH_STENCIL_WRITE: Self = _

Read-write depth stencil usage

pub const STORAGE_READ: Self = _

Read-only storage buffer usage. Corresponds to a UAV in d3d, so is exclusive, despite being read only.

pub const STORAGE_READ_WRITE: Self = _

Read-write or write-only storage buffer usage.

pub const INCLUSIVE: Self = _

The combination of states that a texture may be in at the same time.

pub const EXCLUSIVE: Self = _

The combination of states that a texture must exclusively be in.

pub const ORDERED: Self = _

The combination of all usages that the are guaranteed to be be ordered by the hardware. If a usage is ordered, then if the texture state doesn’t change between draw calls, there are no barriers needed for synchronization.

pub const COMPLEX: Self = _

Flag used by the wgpu-core texture tracker to say a texture is in different states for every sub-resource

pub const UNKNOWN: Self = _

Flag used by the wgpu-core texture tracker to say that the tracker does not know the state of the sub-resource. This is different from UNINITIALIZED as that says the tracker does know, but the texture has not been initialized.

pub const fn empty() -> Self

Returns an empty set of flags.

pub const fn all() -> Self

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

pub const fn from_bits(bits: u16) -> Option<Self>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: u16) -> Self

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u16) -> Self

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 is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

Returns true if there are flags common to both self and other.

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

Returns true if all of the flags in other are contained within self.

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

Inserts or removes the specified flags depending on the passed value.

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

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: Self) -> Self

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: Self) -> Self

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: Self) -> Self

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) -> Self

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.
