Methods

impl nsIDirectoryServiceProvider

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

Cast this nsIDirectoryServiceProvider to one of its base interfaces.

impl nsIDirectoryServiceProvider

pub unsafe fn GetFile(
    &self,
    prop: *const c_char,
    persistent: *mut bool,
    _retval: *mut *const nsIFile
) -> nsresult

/**
  * getFile
  *
  * Directory Service calls this when it gets the first request for
  * a prop or on every request if the prop is not persistent.
  *
  * @param prop         The symbolic name of the file.
  * @param persistent   TRUE - The returned file will be cached by Directory
  *                     Service. Subsequent requests for this prop will
  *                     bypass the provider and use the cache.
  *                     FALSE - The provider will be asked for this prop
  *                     each time it is requested.
  *
  * @return             The file represented by the property.

Trait Implementations

impl XpCom for nsIDirectoryServiceProvider

const IID: nsIID

IID: nsIID = nsID(3153644208, 54330, 4563, [140, 194, 0, 96, 151, 146, 39, 140])

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 nsIDirectoryServiceProvider

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIDirectoryServiceProvider

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
