Enum Fidelity 

#[non_exhaustive]
pub enum Fidelity {
    Degraded,
    Dropped,
    AttrsDegraded,
    AttrsDropped,
}

How much of a node survives a conversion.

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.

Degraded

Something is emitted, but the target’s parser reads it back as a DIFFERENT kind. The content survives; its meaning does not.

Dropped

Nothing is emitted at all: the node and its subtree leave no trace.

AttrsDegraded

Some of the node’s attributes are written where the target’s parser does not read them back as that node’s — djot spells a heading’s on its text, AsciiDoc moves a section title’s onto the section. Independent of the node’s own answer: a node that degrades and still has its attributes written — Markdown’s <div lang=…> for a section it cannot spell — is reported twice at the same path, Degraded and then this. Which keys is not carried across the C boundary: the node at Warning::path has them, and a consumer that wants the list reads them from the tree.

AttrsDropped

Some of the node’s attributes are not written at all. Never reported beside Dropped: nothing of a dropped node is written, so that one variant is the whole answer.
