pub trait WasiView: IoView {
// Required method
fn ctx(&mut self) -> &mut WasiCtx;
}Expand description
A trait which provides access to the WasiCtx inside the embedder’s T
of Store<T>.
This crate’s WASI Host implementations depend on the contents of
WasiCtx. The T type Store<T> is defined in each
embedding of Wasmtime. These implementations are connected to the
Linker<T> by the
add_to_linker_sync and
add_to_linker_async functions.
The WasiView trait implies the IoView trait, so each T must
also contain a ResourceTable and impl IoView.
§Example
use wasmtime_wasi::{WasiCtx, ResourceTable, WasiView, IoView, WasiCtxBuilder};
struct MyState {
ctx: WasiCtx,
table: ResourceTable,
}
impl IoView for MyState {
fn table(&mut self) -> &mut ResourceTable { &mut self.table }
}
impl WasiView for MyState {
fn ctx(&mut self) -> &mut WasiCtx { &mut self.ctx }
}
