Methods

impl nsIExternalHelperAppService

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

Cast this nsIExternalHelperAppService to one of its base interfaces.

impl nsIExternalHelperAppService

    &self,

    aWindowContext: *const nsIInterfaceRequestor,
    _retval: *mut *const nsIStreamListener
) -> nsresult

/**
   * Binds an external helper application to a stream listener. The caller
   * should pump data into the returned stream listener. When the OnStopRequest
   * is issued, the stream listener implementation will launch the helper app
   * with this data.
   * @param aMimeContentType The content type of the incoming data
   * @param aRequest The request corresponding to the incoming data
   * @param aContentContext Used in processing content document refresh
   *  headers after target content is downloaded. Note in e10s land
   *  this is likely a CPOW that points to a window in the child process.
   * @param aForceSave True to always save this content to disk, regardless of
   *  nsIMIMEInfo and other such influences.
   * @param aWindowContext Used in parenting helper app dialogs, usually
   *  points to the parent browser window. This parameter may be null,
   *  in which case dialogs will be parented to aContentContext.
   * @return A nsIStreamListener which the caller should pump the data into.

Trait Implementations

impl XpCom for nsIExternalHelperAppService

const IID: nsIID

IID: nsIID = nsID(508508897, 46903, 17183, [169, 93, 49, 250, 141, 167, 1, 153])

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 nsIExternalHelperAppService

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsIExternalHelperAppService

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
