pub struct GpuReadback { /* private fields */ }Expand description
GPU readback handle for async data retrieval.
Implementations§
Source§impl GpuReadback
impl GpuReadback
Sourcepub fn from_texture(
context: Arc<GraphicsContext>,
texture: &Texture,
) -> Result<Self, ReadbackError>
pub fn from_texture( context: Arc<GraphicsContext>, texture: &Texture, ) -> Result<Self, ReadbackError>
Create a readback from a texture.
This copies the texture to a staging buffer for CPU readback.
Sourcepub fn read(&self) -> Result<Vec<u8>, ReadbackError>
pub fn read(&self) -> Result<Vec<u8>, ReadbackError>
Read data from GPU (blocking).
Returns raw RGBA bytes. Note: This is a simplified blocking implementation. For async usage, consider wrapping in async runtime.
Sourcepub fn dimensions(&self) -> (u32, u32)
pub fn dimensions(&self) -> (u32, u32)
Get the dimensions (width, height).
Sourcepub fn format(&self) -> TextureFormat
pub fn format(&self) -> TextureFormat
Get the texture format.
