Methods

impl nsIGeolocationProvider

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

Cast this nsIGeolocationProvider to one of its base interfaces.

impl nsIGeolocationProvider

pub unsafe fn Startup(&self) -> nsresult

/**
   * Start up the provider.  This is called before any other
   * method.  may be called multiple times.
   */

pub unsafe fn Watch(&self, callback: *const nsIGeolocationUpdate) -> nsresult

/**
   * watch
   * When a location change is observed, notify the callback.
   */

Trait Implementations

impl XpCom for nsIGeolocationProvider

const IID: nsIID

IID: nsIID = nsID(2890535739, 40850, 20348, [179, 105, 212, 12, 182, 177, 118, 80])

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 nsIGeolocationProvider

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIGeolocationProvider

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
