    Js {

The type of sink algorithms we are using.

Variants

Js

Algorithms are provided by Js callbacks.

Fields

Transfer

Algorithms supporting streams transfer are implemented in Rust. The promise and port used in those algorithms are stored here.

Fields

backpressure_promise: &'a Rc<RefCell<Option<TracedPromise>>>

port: &'a MessagePort

Transform(&'a TransformStream, &'a RootedPromise)

Algorithms supporting transform streams are implemented in Rust.

Implementations

Trait Implementations

impl From<UnderlyingSinkTypeRef<'_>> for UnderlyingSinkType

fn from(sink_type: UnderlyingSinkTypeRef<'_>) -> Self
