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 reuse 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.

Implementations§

source§

impl Tree

source

pub fn verify(&self, use_objects: bool, objects: impl Find) -> Result<(), Error>

Validate the correctness of this instance. If use_objects is true, then objects will be used to access all objects.

source§

impl Tree

source

pub fn write_to(&self, out: impl Write) -> Result<(), Error>

Serialize this instance to out.
