type Tree ¶

type Tree struct {
	// contains filtered or unexported fields
}

Tree is a high-level structure that abstract the management of the AVL away from the snapshot engine. It ensure the snapshot and metadata databases are in-sync, and old snapshots are removed when exceeding the maximum number to keep configured. When created, it will automatically remove old local snapshots and load the ones left. When the tree is no longer used, the resources it holds must be released by calling Release().
