Available on crate feature webc_runner_rt_wcgi only.

Callbacks that are triggered at various points in the lifecycle of a runner and any WebAssembly instances it may start.

Provided Methods

fn started(&self, _abort: AbortHandle)

A callback that is called whenever the server starts.

fn on_stderr(&self, _stderr: &[u8])

Data was written to stderr by an instance.

fn on_stderr_error(&self, _error: Error)

Reading from stderr failed.

fn recycle_env<'life0, 'async_trait>( &'life0 self, conf: RecycleEnvConfig, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

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

Recycle the WASI environment

fn create_env<'life0, 'async_trait>( &'life0 self, conf: CreateEnvConfig, ) -> Pin<Box<dyn Future<Output = Result<CreateEnvResult>> + Send + 'async_trait>>

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