Struct ImageSample 

pub struct ImageSample<R> {
    pub texture: R,
    pub sampler: R,
    pub dim: Dim,
    pub coord: [f32; 3],
    pub layer: Option<f32>,
    pub lod: ImageLod,
    pub offset: [i32; 3],
    pub gather: Option<u8>,
    pub depth_ref: Option<f32>,
    pub depth: bool,
}

A sample of any texture: 1D, 2D, 3D, cube, arrayed, with an offset, a gather or a comparison.

Fields

texture: R

The texture sampled: an interface Element or a bind slot, as R says.

sampler: R

The sampler, named the same way.

dim: Dim

The texture’s shape.

coord: [f32; 3]

The coordinate’s components (1D: x; 2D: x, y; 3D and cube: x, y, z); the rest 0.

layer: Option<f32>

An array’s layer, as the program gives it (already rounded and clamped to 0 or more).

lod: ImageLod

How the level of detail is picked.

offset: [i32; 3]

The constant texel offset (0 where the program states none).

gather: Option<u8>

A gather: the component (0 to 3) whose four texels are returned.

depth_ref: Option<f32>

A comparison sample’s reference value.

depth: bool

The texture is a depth texture: the first lane of the result is its (compared) depth.
