Enum FragReuseUpdate 

#[non_exhaustive]
pub enum FragReuseUpdate {
    None,
    Rewrite(Arc<TaggedRewriteAssembly>),
    Trim,
}

What the commit path settled about the fragment reuse entry for one attempt. In-memory only, like the rewrite intent it carries.

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.

None

Nothing was prepared for the entry. A tagged entry arriving on a Rewrite, or a CreateIndex touching a tagged entry, is refused: without the commit path’s derivation such a shape is a pre-assembled snapshot that may splice away records a concurrent writer appended.

Rewrite(Arc<TaggedRewriteAssembly>)

A Rewrite on a tagged history: the entry the commit path assembled for THIS manifest, merging the records the operation’s entry adds onto the current entry and validating them.

Trim

A trim of the tagged entry derived by the reuse index cleanup against the current entry at commit time.
