Enum StageFailure 

pub enum StageFailure {
    Unavailable(Error),
    Unverifiable(Error),
}

Why a row the signed index names could not be staged.

The two are not the same failure and must not be handled the same way. Bytes that never arrived are the ordinary state of a cache: the crate has not been built for this slice yet, the edge is unreachable, GHCR returned a 404. Bytes that arrived and then failed the digest, identity or signature check are not ordinary at all — the signed index vouched for that artifact, so either the publisher produced something it cannot stand behind or someone has write access to the registry they should not have. Compiling quietly past that would hide the one class of bug the whole verification chain exists to surface, and it would hide it on the machine that produces what every user installs.

Variants

Unavailable(Error)

The bundle never arrived. The unit compiles; nothing is wrong.

Unverifiable(Error)

The bundle arrived and did not verify against what the signed index vouches for.
