Struct wasmtime_wasi::preview2::pipe::AsyncWriteStream

pub struct AsyncWriteStream { /* private fields */ }

Provides a HostOutputStream impl from a tokio::io::AsyncWrite impl

Implementations

impl AsyncWriteStream

pub fn new<T: AsyncWrite + Send + Sync + Unpin + 'static>(writer: T) -> Self

Create a AsyncWriteStream. In order to use the HostOutputStream impl provided by this struct, the argument must impl tokio::io::AsyncWrite.

Trait Implementations

impl Drop for AsyncWriteStream

fn drop(&mut self)

Executes the destructor for this type.

impl HostOutputStream for AsyncWriteStream

fn write(&mut self, bytes: Bytes) -> Result<(usize, StreamState), Error>

Write bytes. On success, returns the number of bytes written. Important: this write must be non-blocking!

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

Check for write readiness: this method blocks until the stream is ready for writing.

fn splice( &mut self, src: &mut dyn HostInputStream, nelem: usize ) -> Result<(usize, StreamState), Error>

Transfer bytes directly from an input stream to an output stream. Important: this splice must be non-blocking!

fn write_zeroes(&mut self, nelem: usize) -> Result<(usize, StreamState), Error>

Repeatedly write a byte to a stream. Important: this write must be non-blocking!
