Enum FileTreeNode 

pub enum FileTreeNode {
    File {
        contents: Vec<u8>,
    },
    Directory {
        files: HashMap<String, FileTreeNode>,
    },
}

A node in the file tree structure

Variants

File

A file with its contents

Fields

contents: Vec<u8>

The file contents as bytes or UTF-8 string

Directory

A directory containing other files and directories

Fields

files: HashMap<String, FileTreeNode>

The files and subdirectories in this directory

Implementations

impl FileTreeNode

pub fn get_node<P: AsRef<Path>>(&self, path: P) -> Option<&FileTreeNode>

Get a file or directory node by path

pub fn get_file<P: AsRef<Path>>(&self, path: P) -> Option<&[u8]>

Get file contents by path

pub fn file_exists<P: AsRef<Path>>(&self, path: P) -> bool

Check if a file exists at the given path

pub fn dir_exists<P: AsRef<Path>>(&self, path: P) -> bool

Check if a directory exists at the given path

pub fn list_files<P: AsRef<Path>>(&self, dir_path: P) -> Vec<String>

List all files in a directory (non-recursive)

pub fn list_subdirectories<P: AsRef<Path>>(&self, dir_path: P) -> Vec<String>

List all subdirectories in a directory (non-recursive)

pub fn insert<P: AsRef<Path>>( &mut self, path: P, node: FileTreeNode, ) -> Result<(), Box<dyn StdError + Send + Sync>>

Insert a file or directory at the given path

pub fn flatten(&self) -> Vec<(String, Vec<u8>)>

Flatten the tree into (path, contents) pairs — the inverse of building a tree by insert-ing each path. Paths are "/"-joined and relative (no leading slash), exactly the key shape the WASM Quill.fromTree boundary consumes, so from_tree(flatten(t)) round-trips every file. Output is sorted by path for deterministic ordering (the construction side stores children in a HashMap, which has no inherent order).

Only files are emitted: an EMPTY directory yields no entry and so is not reconstructed by a flatten → insert round trip. This is intentional — quill bundles are file-addressed and nothing in load/render depends on empty directories — but it means the round trip preserves file contents, not exact directory structure.

pub fn print_tree(&self) -> String
