Trait TextureAllocator 

pub trait TextureAllocator {
    type Texture;
    type View;

    // Required method
    fn allocate_texture(
        &self,
        desc: &TextureDesc,
    ) -> (Self::Texture, Self::View);
}

Creates the texture/view pair a TexturePool hands out.

Exists so the pool takes an allocation capability instead of a wgpu::Device: a host test implements it with a counter and plain stand-in values, which is what makes “how many textures did 400 resizes actually allocate?” answerable with no GPU. wgpu::Device is the only production implementation.

Required Associated Types

type Texture

The allocated texture — wgpu::Texture in production.

type View

A full-extent view of Self::Texture — wgpu::TextureView in production.

Required Methods

fn allocate_texture(&self, desc: &TextureDesc) -> (Self::Texture, Self::View)

Creates a texture matching desc plus a full-extent view of it.

Named allocate_texture rather than create_texture so it never shadows wgpu::Device’s inherent method of that name.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types
