Struct task_fs::MmiDir

pub struct MmiDir { /* private fields */ }

Lazily computed directory that contains subfiles and directories relevant to the task’s memory management information.

Implementations

impl MmiDir

pub fn new(task_id: usize, taskref: WeakTaskRef) -> MmiDir

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

Trait Implementations

impl Directory for MmiDir

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, child_name: &str) -> Option<FileOrDir>

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

fn remove(&mut self, _: &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 MmiDir

fn get_absolute_path(&self) -> String

Recursively gets the absolute pathname as a String

fn get_name(&self) -> String

Returns the string name of the node

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

Returns the parent directory of the current node.

fn set_parent_dir(&mut self, _: WeakDirRef)

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