Enum PipeSrc 

pub enum PipeSrc<'a> {
    Solid(&'a [u8]),
    Pattern(&'a dyn Pattern),
}

Source colour for a single paint operation.

The source is resolved once per span and may be a flat colour (most common) or a dynamic Pattern queried per-pixel.

Variants

Solid(&'a [u8])

Flat colour: ncomps bytes, already in device space.

Pattern(&'a dyn Pattern)

Dynamic pattern source — fill_span is called per output row.
