Implementations

impl QueueWithSizes

pub(crate) fn dequeue_value( &mut self, cx: SafeJSContext, rval: Option<MutableHandleValue<'_>>, can_gc: CanGc, )

https://streams.spec.whatwg.org/#dequeue-value A none rval means we’re dequeing the close sentinel, which should never be made available to script.

pub(crate) fn enqueue_value_with_size( &mut self, value: EnqueuedValue, ) -> Result<(), Error>

https://streams.spec.whatwg.org/#enqueue-value-with-size

pub(crate) fn is_empty(&self) -> bool

pub(crate) fn peek_queue_value( &self, cx: SafeJSContext, rval: MutableHandleValue<'_>, can_gc: CanGc, ) -> bool

https://streams.spec.whatwg.org/#peek-queue-value Returns whether value is the close sentinel.

fn get_in_memory_bytes(&self) -> Option<Vec<u8>>

Trait Implementations

impl Default for QueueWithSizes

fn default() -> QueueWithSizes

Returns the “default value” for a type.

impl MallocSizeOf for QueueWithSizes

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl Traceable for QueueWithSizes

unsafe fn trace(&self, tracer: *mut JSTracer)

Trace self.
