Struct VirtualResource 

pub struct VirtualResource { /* private fields */ }

Represents a virtual resource in the system, uniquely identified by a string.

Note that the resource named swapchain is assumed to always be the swapchain resource for presenting.

Implementations

impl VirtualResource

pub fn image(name: impl Into<String>) -> Self

Create a new image virtual resource.

pub fn buffer(name: impl Into<String>) -> Self

Create a new buffer virtual resource.

pub fn upgrade(&self) -> Self

‘Upgrades’ the resource to a new version of itself. This is used to obtain the virtual resource name of an input resource after a task completes.

pub fn name(&self) -> &str

Returns the full, original name of the resource

pub fn version(&self) -> usize

Returns the version of a resource, the larger this the more recent the version of the resource is.

pub fn is_source(&self) -> bool

Returns true if the resource is a source resource, e.g. an instance that does not depend on a previous pass.

pub fn is_associated_with(&self, rhs: &VirtualResource) -> bool

Check if these virtual resources refer to the same physical resource

pub fn is_older(lhs: &VirtualResource, rhs: &VirtualResource) -> bool

One virtual resource is older than another if it has less ‘+’ symbols.

pub fn is_younger(lhs: &VirtualResource, rhs: &VirtualResource) -> bool

Note that this is not the same as inverting the result of as_older(), for the same exact state of the resource, both of these functions should return false (they decide whether resources are strictly older or younger than each other).

pub fn resource_type(&self) -> ResourceType

Get the resource type of this virtual resource

pub fn uid(&self) -> String

Get the uid of this virtual resource

Trait Implementations

impl Clone for VirtualResource

fn clone(&self) -> VirtualResource

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for VirtualResource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VirtualResource

fn default() -> VirtualResource

Returns the “default value” for a type.

impl Display for VirtualResource

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for VirtualResource

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VirtualResource

fn eq(&self, other: &VirtualResource) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
