Struct wasmtime_wasi_http::body::BodyWriteStream

pub struct BodyWriteStream { /* private fields */ }

Provides a HostOutputStream impl from a tokio::sync::mpsc::Sender.

Implementations

impl BodyWriteStream

pub fn new(write_budget: usize, writer: Sender<Bytes>) -> Self

Create a BodyWriteStream.

Trait Implementations

impl HostOutputStream for BodyWriteStream

fn write(&mut self, bytes: Bytes) -> Result<(), StreamError>

Write bytes after obtaining a permit to write those bytes

fn flush(&mut self) -> Result<(), StreamError>

Trigger a flush of any bytes buffered in this stream implementation.

fn check_write(&mut self) -> Result<usize, StreamError>

Returns the number of bytes that are ready to be written to this stream.

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

Repeatedly write a byte to a stream. Important: this write must be non-blocking! Returning an Err which downcasts to a StreamError will be reported to Wasm as the empty error result. Otherwise, errors will trap.

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

Simultaneously waits for this stream to be writable and then returns how much may be written or the last error that happened.
