Struct Tree

Source
pub struct Tree {
    pub name: SmallVec<[u8; 23]>,
    pub id: ObjectId,
    pub num_entries: Option<u32>,
    pub children: Vec<Tree>,
}
Expand description

A structure to associate object ids of a tree with sections in the index entries list.

It allows to more quickly build trees by avoiding as it can quickly re-use portions of the index and its associated tree ids if there was no change to them. Portions of this tree are invalidated as the index is changed.

Fields§

§name: SmallVec<[u8; 23]>

The name of the tree/directory, or empty if it’s the root tree.

§id: ObjectId

The id of the directory tree of the associated tree object.

§num_entries: Option<u32>

The amount of non-tree items in this directory tree, including sub-trees, recursively. The value of the top-level tree is thus equal to the value of the total amount of entries. If None, the tree is considered invalid and needs to be refreshed

§children: Vec<Tree>

The child-trees below the current tree.
