#[repr(transparent)]pub struct WasiImpl<T>(pub T);
Expand description
A small newtype wrapper which serves as the basis for implementations of
Host
WASI traits in this crate.
This type is used as the basis for the implementation of all Host
traits
generated by bindgen!
for WASI interfaces. This is used automatically with
add_to_linker_sync
and
add_to_linker_async
.
This type is otherwise provided if you’re calling the add_to_linker
functions generated by bindgen!
from the bindings
module. In this situation you’ll want to create a value of
this type in the closures added to a Linker
.

fn subscribe( &mut self, stream: Resource<InputStream>, ) -> Result<Resource<Pollable>>
Create a

The created pollable
is a child resource of the input-stream

Implementations may trap if the input-stream
is dropped before
all derived pollable
