Struct TextureMapping 

pub struct TextureMapping {
    pub texture: Handle<GlobalVariable>,
    pub sampler: Option<Handle<GlobalVariable>>,
}

Available on crate feature unstable-wgpu-27 only.

Mapping between a texture and its sampler, if it exists.

GLSL pre-Vulkan has no concept of separate textures and samplers. Instead, everything is a gsamplerN where g is the scalar type and N is the dimension. But naga uses separate textures and samplers in the IR, so the backend produces a FastHashMap with the texture name as a key and a TextureMapping as a value. This way, the user knows where to bind.

Storage images produce gimageN and don’t have an associated sampler, so the sampler field will be None.

Fields

texture: Handle<GlobalVariable>

Handle to the image global variable.

sampler: Option<Handle<GlobalVariable>>

Handle to the associated sampler global variable, if it exists.
