Struct DirectoryLayout 

pub struct DirectoryLayout {
    pub name: String,
    pub files: Vec<FileLayout>,
    pub subdirs: Vec<DirectoryLayout>,
    pub timestamps: Timestamps,
    pub attributes: u32,
    pub extent: Option<Extent>,
}

Directory layout (tree of files).

Represents a complete directory tree with pre-calculated extents for all files. Used for metadata-only writing operations.

Fields

name: String

Directory name (empty string for root).

files: Vec<FileLayout>

Files in this directory.

subdirs: Vec<DirectoryLayout>

Subdirectories.

timestamps: Timestamps

Directory timestamps.

attributes: u32

Filesystem-specific attribute flags.

extent: Option<Extent>

Extent for the directory entry itself (if applicable).

Implementations

impl DirectoryLayout

pub fn new(name: impl Into<String>) -> Self

Creates a new empty directory layout.

pub fn root() -> Self

Creates a root directory layout (empty name).

pub fn add_file(&mut self, file: FileLayout)

Adds a file to this directory.

pub fn add_subdir(&mut self, subdir: DirectoryLayout)

Adds a subdirectory to this directory.

pub fn with_timestamps(self, timestamps: Timestamps) -> Self

Sets the timestamps.

pub fn with_extent(self, extent: Extent) -> Self

Sets the extent for this directory entry.

pub fn file_count(&self) -> usize

Returns the total number of files in this directory (not recursive).

pub fn subdir_count(&self) -> usize

Returns the total number of subdirectories in this directory (not recursive).

pub fn entry_count(&self) -> usize

Returns the total number of entries (files + subdirs).

pub fn iter_files(&self) -> impl Iterator<Item = (&str, &FileLayout)>

Returns an iterator over all files (recursive, depth-first).

pub fn find_file(&self, path: &str) -> Option<&FileLayout>

Finds a file by path (e.g., “docs/readme.txt”).

pub fn find_file_mut(&mut self, path: &str) -> Option<&mut FileLayout>

Finds a mutable file reference by path.

pub fn get_or_create_dir(&mut self, path: &str) -> &mut DirectoryLayout

Finds or creates a subdirectory by path.

pub fn remove_file(&mut self, path: &str) -> Option<FileLayout>

Removes a file by path. Returns the removed file if found.

Trait Implementations

impl Clone for DirectoryLayout

fn clone(&self) -> DirectoryLayout

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DirectoryLayout

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

Formats the value using the given formatter.

impl Default for DirectoryLayout

fn default() -> DirectoryLayout

Returns the “default value” for a type.
