Struct Tree 

pub struct Tree {
    pub nodes: Vec<Node>,
}

A Tree is a list of Nodes

Fields

nodes: Vec<Node>

The nodes contained in the tree.

This is usually sorted by Node.name(), i.e. by the node name as OsString

Implementations

impl Tree

pub(crate) const fn new() -> Self

Creates a new Tree with no nodes.

pub(crate) fn add(&mut self, node: Node)

Adds a node to the tree.

Arguments

• node - The node to add.

pub fn serialize(&self) -> Result<(Vec<u8>, TreeId), TreeErrorKind>

Serializes the tree in JSON format like restic does.

Returns

A tuple of the serialized tree as Vec<u8> and the tree’s ID, i.e. the hash of the serialized tree.

Errors

• If the tree could not be serialized. This should never happen.

pub(crate) fn from_backend( be: &impl DecryptReadBackend, index: &impl ReadGlobalIndex, id: TreeId, ) -> RusticResult<Self>

Deserializes a tree from the backend.

Arguments

• be - The backend to read from.
• id - The ID of the tree to deserialize.

Errors

• If the tree ID is not found in the backend.
• If deserialization fails.

Returns

The deserialized tree.

pub(crate) fn node_from_path( be: &impl DecryptReadBackend, index: &impl ReadGlobalIndex, id: TreeId, path: &Path, ) -> RusticResult<Node>

Creates a new node from a path.

Arguments

• be - The backend to read from.
• id - The ID of the tree to deserialize.
• path - The path to create the node from.

Errors

• If the path is not a directory.
• If the path is not found.
• If the path is not UTF-8 conform.

pub(crate) fn find_nodes_from_path( be: &impl DecryptReadBackend, index: &impl ReadGlobalIndex, ids: impl IntoIterator<Item = TreeId>, path: &Path, ) -> RusticResult<FindNode>

pub(crate) fn find_matching_nodes( be: &impl DecryptReadBackend, index: &impl ReadGlobalIndex, ids: impl IntoIterator<Item = TreeId>, matches: &impl Fn(&Path, &Node) -> bool, ) -> RusticResult<FindMatches>

Trait Implementations

impl Clone for Tree

fn clone(&self) -> Tree

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Tree

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Tree

fn default() -> Tree

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Tree

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IntoIterator for Tree

type Item = Node

The type of the elements being iterated over.

type IntoIter = IntoIter<Node>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl Serialize for Tree

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
