Struct FileTree 

pub struct FileTree { /* private fields */ }

A virtual filesystem snapshot: path → CAS blob hash.

Uses BTreeMap for deterministic ordering (important for hashing and diffs).

Implementations

impl FileTree

pub fn empty() -> Self

Create an empty file tree.

pub fn from_map(entries: BTreeMap<String, Hash>) -> Self

Create a file tree from a pre-populated map.

pub fn get(&self, path: &str) -> Option<&Hash>

Get the blob hash for a given path.

pub fn contains(&self, path: &str) -> bool

Check if a path exists in the tree.

pub fn insert(&mut self, path: String, hash: Hash)

Insert or update a path → hash mapping.

pub fn remove(&mut self, path: &str) -> Option<Hash>

Remove a path from the tree.

pub fn rename(&mut self, old_path: &str, new_path: String) -> Option<Hash>

Rename a path in the tree.

pub fn len(&self) -> usize

Get the number of files in the tree.

pub fn is_empty(&self) -> bool

Check if the tree is empty.

pub fn iter(&self) -> impl Iterator<Item = (&String, &Hash)>

Iterate over all (path, hash) entries in sorted order.

pub fn paths(&self) -> Vec<&String>

Get all paths in the tree (sorted).

pub fn content_hash(&self) -> Hash

Compute a BLAKE3 hash of the entire tree state.

This provides a content-addressed identifier for a snapshot.

Trait Implementations

impl Clone for FileTree

fn clone(&self) -> FileTree

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FileTree

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

Formats the value using the given formatter.

impl Default for FileTree

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FileTree

fn eq(&self, other: &FileTree) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
