Struct PoolKey 

pub struct PoolKey {
    pub width: u32,
    pub height: u32,
    pub format: TextureFormat,
    pub usage: TextureUsages,
    pub sample_count: u32,
}

The configuration a pooled texture is interchangeable within: two requests that produce the same key may share one texture, and two that do not never can.

width/height are the quantized extent (quantize_extent), and usage is the effective usage (effective_usage) rather than the requested one, because those are what the pooled texture was actually created with.

Fields

width: u32

Quantized width in texels.

height: u32

Quantized height in texels.

format: TextureFormat

The texture’s pixel format.

usage: TextureUsages

The usage the texture was created with.

sample_count: u32

The texture’s sample count. Always 1 today (TextureDesc exposes no way to ask for more), and part of the key anyway so a multisampled target could never alias a single-sampled one.
