§listener: MutNullableDom<AudioListener>§in_flight_resume_promises_queue: DomRefCell<VecDeque<(Box<[Rc<Promise>]>, Result<(), Error>)>>

Resume promises which are soon to be fulfilled by a queued task.

§pending_resume_promises: DomRefCell<Vec<Rc<Promise>>>

§decode_resolvers: DomRefCell<HashMap<String, DecodeResolver>>§sample_rate: f32

§state: Cell<AudioContextState>

https://webaudio.github.io/web-audio-api/#dom-baseaudiocontext-state Although servo-media already keeps track of the control thread state, we keep a state flag here as well. This is so that we can synchronously throw when trying to do things on the context when the context has just been “closed()”.

Implementations§

source§

impl BaseAudioContext

source

pub fn new_inherited(
    options: BaseAudioContextOptions,
    pipeline_id: PipelineId
) -> BaseAudioContext

source

pub fn is_offline(&self) -> bool

Tells whether this is an OfflineAudioContext or not.

source

pub fn audio_context_impl(&self) -> Arc<Mutex<AudioContext>>

source

pub fn destination_node(&self) -> NodeId

source

pub fn listener(&self) -> NodeId

source

pub fn is_allowed_to_start(&self) -> bool

source

fn push_pending_resume_promise(&self, promise: &Rc<Promise>)

source

fn take_pending_resume_promises(&self, result: Result<(), Error>)

Takes the pending resume promises.

The result with which these promises will be fulfilled is passed here and this method returns nothing because we actually just move the current list of pending resume promises to the in_flight_resume_promises_queue field.

Each call to this method must be followed by a call to fulfill_in_flight_resume_promises, to actually fulfill the promises which were taken and moved to the in-flight queue.

source

fn fulfill_in_flight_resume_promises<F>(&self, f: F)where
    F: FnOnce(),

Fulfills the next in-flight resume promises queue after running a closure.

See the comment on take_pending_resume_promises for why this method does not take a list of promises to fulfill. Callers cannot just pop the front list off of in_flight_resume_promises_queue and later fulfill the promises because that would mean putting #[allow(unrooted_must_root)] on even more functions, potentially hiding actual safety bugs.

source

pub fn control_thread_state(&self) -> ProcessingState

Control thread processing state

source

pub fn set_state_attribute(&self, state: AudioContextState)

Set audio context state
