Struct ImageData 

pub struct ImageData {
    pub width: u32,
    pub height: u32,
    pub rgba: Arc<[u8]>,
    pub blob: Blob<u8>,
}

Decoded image payload in RGBA8 with top-left origin.

• Shared via Handle<ImageData>; never deep-copied.
• blob is a pre-built peniko::Blob whose stable identity keys a renderer’s image upload cache across frames. Blob cloning is Arc-cheap.

Fields

width: u32

Width in pixels.

height: u32

Height in pixels.

rgba: Arc<[u8]>

RGBA8 pixel buffer in row-major order (width * height * 4 bytes), accessible to consumers other than the renderer, such as the MCP inspector.

blob: Blob<u8>

Pre-built peniko::Blob whose identity is the renderer’s upload cache key.

Trait Implementations

impl AssetSize for ImageData

fn bytes(&self) -> usize

Returns the approximate CPU-side byte cost of this asset, consulted by AssetServer::bytes_used and the LRU eviction sweep.
