Struct ImageEntry 

pub struct ImageEntry {
    pub width: u32,
    pub height: u32,
    pub rgba: Arc<Vec<u8>>,
    pub rev: u32,
    pub backing: ImageBacking,
    /* private fields */
}

An RGBA image registered by the host (rendering lands in a later pass).

Fields

width: u32

height: u32

rgba: Arc<Vec<u8>>

Shared rather than owned so a frame’s display list can hand a backend the pixels of a texture-backed image without copying them (DisplayList::texture_pixels): an update replaces the Arc, and a backend mid-upload keeps the old one alive until it is done.

rev: u32

Moves on every Resources::update_image; a backend re-uploads a texture-backed image when the revision it uploaded is behind.

backing: ImageBacking

Where the pixels live on the GPU.
