Struct vfs_node::VFSDirectory

pub struct VFSDirectory {
    pub name: String,
    pub children: BTreeMap<String, FileOrDir>,
    pub parent: WeakDirRef,
}

A struct that represents a node in the VFS

Fields

name: String

The name of the directory

children: BTreeMap<String, FileOrDir>

A list of child filesystem nodes

parent: WeakDirRef

A weak reference to the parent directory

Implementations

impl VFSDirectory

pub fn create(name: String, parent: &DirRef) -> Result<DirRef, &'static str>

Creates a new directory and passes a pointer to the new directory created as output

Trait Implementations

impl Directory for VFSDirectory

fn list(&self) -> Vec<String>

Returns a string listing all the children in the directory

fn insert(&mut self, node: FileOrDir) -> Result<Option<FileOrDir>, &'static str>

Inserts the given new file or directory into this directory. If an existing node has the same name, that node is replaced and returned.

fn get(&self, name: &str) -> Option<FileOrDir>

Gets either the file or directory in this Directory on its name.

fn remove(&mut self, node: &FileOrDir) -> Option<FileOrDir>

Removes a file or directory from this directory and returns it if found. Also, the returned node’s parent directory reference is cleared.

fn get_file( &self, name: &str ) -> Option<Arc<Mutex<dyn File + Send, Spin>, Global>>

Like [Directory::get()], but only looks for files matching the given name in this Directory.

fn get_dir( &self, name: &str ) -> Option<Arc<Mutex<dyn Directory + Send, Spin>, Global>>

Like [Directory::get()], but only looks for directories matching the given name in this Directory.

impl FsNode for VFSDirectory

fn get_parent_dir(&self) -> Option<DirRef>

Returns a pointer to the parent if it exists

fn get_name(&self) -> String

Returns the string name of the node

fn set_parent_dir(&mut self, new_parent: WeakDirRef)

Sets this node’s parent directory. This is useful for ensuring correctness when inserting or removing files or directories from their parent directory.

fn get_absolute_path(&self) -> String

Recursively gets the absolute pathname as a String
