Enum TextureSource 

pub enum TextureSource {
    Texture {
        texture: Entity,
        sampler: SamplerState,
    },
    Default {
        value: [f32; 4],
        why: String,
    },
    Frame(FrameTexture),
    Missing {
        why: String,
    },
    Target {
        view: TargetView,
    },
}

What a texture slot samples.

Variants

Texture

A texture entity (core.texture, core.texture_layers or core.texture_file), with the sampler state stored with it.

Fields

texture: Entity

sampler: SamplerState

Default

No texture; the slot reads this value everywhere, and why.

Fields

value: [f32; 4]

why: String

Frame(FrameTexture)

An image of the frame being drawn, which the consumer supplies.

Missing

Nothing is bound and the source says no default: a consumer must not invent one. The reason retains the source’s resource identity and the missing evidence, so consumers can explain the refusal.

Fields

why: String

Target

A view of one of the frame’s own targets: only in the binding of a step of the frame’s core.render_graph (crate::render_graph), whose targets these are. A material’s binding never states one. It is read through the program’s samplers, whose states the stage states (StageBinding::samplers): a sampler’s state belongs to the sampler, which one texture may be read through several of.

Fields

view: TargetView

Implementations

impl TextureSource

pub fn spatial_kind(&self) -> SpatialKind

How the bound image moves into a program frame. A source’s own textures and a graph’s own targets are in its programs’ frame already.

Trait Implementations
