Struct wasmtime_wasi::pipe::AsyncReadStream

pub struct AsyncReadStream { /* private fields */ }

Provides a HostInputStream impl from a tokio::io::AsyncRead impl

Implementations

impl AsyncReadStream

pub fn new<T: AsyncRead + Send + Unpin + 'static>(reader: T) -> Self

Create a AsyncReadStream. In order to use the HostInputStream impl provided by this struct, the argument must impl tokio::io::AsyncRead.

Trait Implementations

impl HostInputStream for AsyncReadStream

fn read(&mut self, size: usize) -> Result<Bytes, StreamError>

Reads up to size bytes, returning a buffer holding these bytes on success.

fn skip(&mut self, nelem: usize) -> StreamResult<usize>

Same as the read method except that bytes are skipped.

impl Subscribe for AsyncReadStream

fn ready<'life0, 'async_trait>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

An asynchronous function which resolves when this object’s readiness operation is ready.
