interface nsISpeechService : nsISupports

/**
 * The main interface of a speech synthesis service.
 *
 * A service is responsible for outputting audio.
 * The service dispatches events, starting with dispatchStart() and ending with
 * dispatchEnd or dispatchError().
 * A service must also respond with the currect actions and events in response

Trait Implementations

impl XpCom for nsISpeechService

const IID: nsIID

IID: nsIID = nsID(2608683483, 35071, 17360, [182, 238, 159, 99, 208, 66, 208, 143])

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 nsISpeechService

unsafe fn addref(&self)

Increment the reference count.

unsafe fn release(&self)

Decrement the reference count, potentially freeing backing memory.

impl Deref for nsISpeechService

type Target = nsISupports

The resulting type after dereferencing.

fn deref(&self) -> &nsISupports

Dereferences the value.
