Struct TextureUploader 

pub struct TextureUploader { /* private fields */ }

Helper to upload texture data from CPU to GPU.

Useful for video frame upload or dynamic texture updates.

Implementations

impl TextureUploader

pub fn new( context: &GraphicsContext, width: u32, height: u32, format: TextureFormat, ) -> Self

Create a new texture uploader with the specified dimensions.

Arguments

• context - The graphics context
• width - Texture width in pixels
• height - Texture height in pixels
• format - Texture format (e.g., Rgba8UnormSrgb for standard images)

pub fn upload(&self, context: &GraphicsContext, data: &[u8])

Upload pixel data to the texture.

Arguments

• context - The graphics context
• data - Raw pixel data (must match texture format and dimensions)

pub fn upload_region( &self, context: &GraphicsContext, data: &[u8], x: u32, y: u32, width: u32, height: u32, )

Upload a subregion of the texture.

Arguments

• context - The graphics context
• data - Raw pixel data for the region
• x, y - Top-left corner of the region
• width, height - Dimensions of the region

pub fn resize(&mut self, context: &GraphicsContext, width: u32, height: u32)

Resize the texture (creates a new texture internally).

pub fn view(&self) -> &TextureView

Get the texture view for rendering.

pub fn texture(&self) -> &Texture

Get the underlying texture.

pub fn size(&self) -> (u32, u32)

Get the texture dimensions.

pub fn format(&self) -> TextureFormat

Get the texture format.
