Struct MapVersionId 

pub struct MapVersionId(/* private fields */);

Content-derived identifier for one index snapshot.

The identifier hashes the complete timestamp-free RootManifest, so it includes both the root CID and the tree configuration. Empty trees therefore also have a stable version identifier.

Implementations

impl MapVersionId

pub fn for_tree(tree: &Tree) -> Result<Self, Error>

Compute the stable identifier for a tree handle.

pub fn as_cid(&self) -> &Cid

Borrow the underlying 32-byte content identifier.

pub fn into_cid(self) -> Cid

Consume this identifier and return its underlying CID.
