Enum RasterCause 

#[non_exhaustive]
pub enum RasterCause {
    Transparency,
    UnembeddableFont,
}

Why a page had to be rasterized rather than repaired.

A separate enum rather than a string on Compromise::PageRasterized, because the two causes are acted on differently: a caller converting to A-1b who sees RasterCause::Transparency can reasonably retry at A-2b and keep the vectors, and a program should be able to notice that without matching on prose.

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.

Transparency

The page uses transparency and the level forbids it. A-1b only: A-2b permits transparency, so this cause cannot arise there.

UnembeddableFont

The page draws with a font whose program is not available and which could not be substituted.
