Struct LazyPseudoDirectory 

pub struct LazyPseudoDirectory<T>(/* private fields */);

A pseudo directory that delays constructing a PseudoDirectory until a request is received.

The intended purpose of LazyPseudoDirectory is to save memory when presenting data in a filesystem structure for debug purposes. The directory should not be accessed during regular system usage otherwise no memory savings will occur.

Implementations

impl<T: ToPseudoDirectory> LazyPseudoDirectory<T>

pub fn new(data: T) -> Arc<Self>

pub fn state(&self) -> LazyPseudoDirectoryState<'_, T>

Retrieves either the backing data or the directory depending on whether the directory has been accessed yet.

Trait Implementations

impl<T: ToPseudoDirectory> DirectoryEntry for LazyPseudoDirectory<T>

fn open_entry(self: Arc<Self>, request: OpenRequest<'_>) -> Result<(), Status>

Opens this entry.

fn scope(&self) -> Option<ExecutionScope>

The scope that should own connections to this directory entry, or None if parent scope should be used (the default).

impl<T: ToPseudoDirectory> DirectoryEntryAsync for LazyPseudoDirectory<T>

async fn open_entry_async( self: Arc<Self>, request: OpenRequest<'_>, ) -> Result<(), Status>

Implementers may use this if desired by using the spawn method below.

impl<T> GetEntryInfo for LazyPseudoDirectory<T>

fn entry_info(&self) -> EntryInfo

This method is used to populate ReadDirents() output.
