Struct wasm_streams::writable::IntoAsyncWrite

source · [−]

pub struct IntoAsyncWrite<'writer> { /* private fields */ }

Expand description

An AsyncWrite for the into_async_write method.

This AsyncWrite holds a writer, and therefore locks the WritableStream. When this AsyncWrite is dropped, it also drops its writer which in turn releases its lock.

Implementations

source

impl<'writer> IntoAsyncWrite<'writer>

source

pub async fn abort(self) -> Result<(), JsValue>

Aborts the stream, signaling that the producer can no longer successfully write to the stream.

source

pub async fn abort_with_reason(self, reason: &JsValue) -> Result<(), JsValue>

Aborts the stream, signaling that the producer can no longer successfully write to the stream.
