Struct Texture2DDescriptor 

pub struct Texture2DDescriptor {
    pub width: u32,
    pub height: u32,
    pub format: GpuTextureFormat,
    pub mip_level_count: u32,
    pub sample_count: u32,
}

A 2D texture descriptor for create_texture_2d.

Defaults produce a 1x1 RGBA8 texture with TEXTURE_BINDING | COPY_DST | COPY_SRC usage, which is the right baseline for a sampled color texture that is uploaded to via queue.writeTexture. Override fields after constructing to set mip_level_count, sample_count, or different usage flags.

Fields

width: u32

The texture width in pixels. Must be > 0.

height: u32

The texture height in pixels. Must be > 0.

format: GpuTextureFormat

The texel format, as one of the GpuTextureFormat variants.

mip_level_count: u32

The number of mip levels. 0 is treated as 1.

sample_count: u32

The number of samples per texel (1 for non-MSAA, 4 for MSAA).

Implementations

impl Texture2DDescriptor

Default-construction helper for Texture2DDescriptor.

pub fn default_for(width: u32, height: u32, format: GpuTextureFormat) -> Self

Returns a descriptor with the most common defaults applied.

This is the same as calling the generated new constructor and then explicitly setting the defaults; we provide it so callers can do Texture2DDescriptor::default_for(w, h, format) instead of having to remember which fields to set.

Arguments

• u32 - The texture width in pixels.
• u32 - The texture height in pixels.
• GpuTextureFormat - The texel format.

Returns

• Self - A new descriptor with mip_level_count = 1 and sample_count = 1.
