Trait Implementations

impl HostOutputStream for ErrorStream

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

Write bytes after obtaining a permit to write those bytes

fn flush(&mut self) -> StreamResult<()>

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

fn check_write(&mut self) -> StreamResult<usize>

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

fn blocking_write_and_flush<'life0, 'async_trait>( &'life0 mut self, bytes: Bytes, ) -> Pin<Box<dyn Future<Output = Result<(), StreamError>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Send + 'async_trait,

Perform a write of up to 4096 bytes, and then flush the stream. Block until all of these operations are complete, or an error occurs.

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

where 'life0: 'async_trait, Self: Send + 'async_trait,

Perform a write of up to 4096 zeroes, and then flush the stream. Block until all of these operations are complete, or an error occurs.

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.

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

where 'life0: 'async_trait, Self: Send + 'async_trait,

Cancel any asynchronous work and wait for it to wrap up.

impl Subscribe for ErrorStream

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.
