Struct wasmtime_wasi::preview2::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 + Sync + 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 Drop for AsyncReadStream

fn drop(&mut self)

Executes the destructor for this type.

impl HostInputStream for AsyncReadStream

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

Read bytes. On success, returns a pair holding the number of bytes read and a flag indicating whether the end of the stream was reached. Important: this read 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 read readiness: this method blocks until the stream is ready for reading.

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

Read bytes from a stream and discard them. Important: this method must be non-blocking!
