This type exposes the internal nodes used in irmin in order to use them during snapshot import and export.

val tree_iteri_unique : ?on_disk:bool -> index -> (Snapshot.t -> unit Lwt.t) -> tree -> int Lwt.t

tree_iteri_unique ?on_disk index f tree traverses tree, applying f to all inodes and contents.

f is called in post-order, that is f is first called on the leaves, and the last call to f is on the root of the tree.

The traversal order is stable.

The traversal skips objects that are structurally equal to objects that were already traversed. In other words, tree_iteri_unique internally uses a hash set in order to guarantee that all the objects passed to f don't hash the same way.

If on_disk is true (by default its false), it uses an on_disk index.

Returns the total number of elements visited.

type import
val v_import : ?in_memory:bool -> index -> import

v_import ?in_memory index creates an importer instance. If in_memory is true, the import will be fully in memory. in_memory is set to false by default.

val save_inode : index -> import -> Snapshot.t -> tree option Lwt.t

save_inode index importer elt saves elt to the store.

val close_import : import -> index -> unit

close importer close the importer instance.
