Enum TreeRead 

pub enum TreeRead {
    Full(Tree),
    Partial(PartialTree),
    Absent,
}

The result of resolving a tree hash that may be held either as the full canonical object or only as a redacted partial projection (HRT1).

A full tree SUPERSEDES a partial for the same hash. Partial is distinct from Absent on purpose: a partial clone that withholds an entry must be distinguishable from a repository that is missing or corrupt, so callers can present “withheld” rather than “gone”.

Variants

Full(Tree)

The full canonical tree is held.

Partial(PartialTree)

Only a redacted partial projection is held: its visible entries carry their preimage and its withheld entries are marked opaque. Verifies against the declared State.tree via PartialTree::reconstruct_root.

Absent

Neither a full tree nor a partial projection is held for this hash.
