Enum AtlasUpdate 

#[non_exhaustive]
pub enum AtlasUpdate {
    Resize {
        width: u32,
        height: u32,
    },
    Write(GlyphUpload),
}

A change the renderer must apply to its atlas texture, in queue order.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Resize

Make the texture at least width x height, keeping existing texels where they are. Always the first update, so the renderer learns the size from the cache itself.

Fields

width: u32

Width in texels.

height: u32

Height in texels.

Write(GlyphUpload)

Copy pixels into the texture.
