interface nsIDirectoryEnumerator : nsISupports

/**
 * This interface provides a means for enumerating the contents of a directory.
 * It is similar to nsISimpleEnumerator except the retrieved entries are QI'ed
 * to nsIFile, and there is a mechanism for closing the directory when the
 * enumeration is complete.

Methods

impl nsIDirectoryEnumerator

pub fn coerce<T: nsIDirectoryEnumeratorCoerce>(&self) -> &T

Cast this nsIDirectoryEnumerator to one of its base interfaces.

impl nsIDirectoryEnumerator

pub unsafe fn GetNextFile(&self, aNextFile: *mut *const nsIFile) -> nsresult

/**
   * Retrieves the next file in the sequence. The "nextFile" element is the
   * first element upon the first call. This attribute is null if there is no
   * next element.
   */

readonly attribute nsIFile nextFile;

pub unsafe fn Close(&self) -> nsresult

/**
   * Closes the directory being enumerated, releasing the system resource.
   * @throws NS_OK if the call succeeded and the directory was closed.
   *         NS_ERROR_FAILURE if the directory close failed.
   *         It is safe to call this function many times.

Trait Implementations

impl XpCom for nsIDirectoryEnumerator

const IID: nsIID

IID: nsIID = nsID(838333614, 26902, 20269, [168, 30, 146, 106, 78, 48, 34, 238])

fn query_interface<T: XpCom>(&self) -> Option<RefPtr<T>>

Perform a QueryInterface call on this object, attempting to dynamically cast it to the requested interface type. Returns Some(RefPtr) if the cast succeeded, and None otherwise.

impl RefCounted for nsIDirectoryEnumerator

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIDirectoryEnumerator

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
