Struct wasm_streams::readable::IntoAsyncRead

source · [−]

pub struct IntoAsyncRead<'reader> { /* private fields */ }

Expand description

An AsyncRead for the into_async_read method.

This AsyncRead holds a reader, and therefore locks the ReadableStream. When this AsyncRead is dropped, it also drops its reader which in turn releases its lock.

Implementations

source

impl<'reader> IntoAsyncRead<'reader>

source

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

Cancels the stream, signaling a loss of interest in the stream by a consumer.

source

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

Cancels the stream, signaling a loss of interest in the stream by a consumer.
