pub trait IoView: Send {
// Required method
fn table(&mut self) -> &mut ResourceTable;
}Expand description
A trait which provides access to the ResourceTable inside the
embedder’s T of Store<T>.
This crate’s WASI Host implementations depend on the contents of
ResourceTable. The T type Store<T> is defined in each
embedding of Wasmtime. These implementations is connected to the
Linker<T> by the
add_to_linker_async function.
§Example
use wasmtime::{Config, Engine};
use wasmtime::component::{ResourceTable, Linker};
use wasmtime_wasi_io::{IoView, add_to_linker_async};
struct MyState {
table: ResourceTable,
}
impl IoView for MyState {
fn table(&mut self) -> &mut ResourceTable { &mut self.table }
}
let mut config = Config::new();
config.async_support(true);
let engine = Engine::new(&config).unwrap();
let mut linker: Linker<MyState> = Linker::new(&engine);
add_to_linker_async(&mut linker).unwrap();
