Enum Failure 

pub enum Failure {
    Absent,
    ObjectType,
    OtherObject,
    Algorithm,
    Hash,
    KeyEncoding,
    Differs,
}

A completed semantic refusal; processing and callback failures use Result.

Variants

Absent

No objectDigestInfo Holder alternative was written.

ObjectType

Written object choice differs from the caller’s explicit object.

OtherObject

otherObjectTypes or otherObjectTypeID is forbidden by this profile.

Algorithm

Known digest algorithm has invalid parameters.

Hash

Digest bits have padding or the wrong fixed algorithm width.

KeyEncoding

Provider rejected the key’s algorithm-specific representation.

Differs

Completed digest comparison found different bytes.
