Struct WasiCli 

pub struct WasiCli;

A helper struct which implements HasData for the wasi:cli APIs.

This can be useful when directly calling add_to_linker functions directly, such as [wasmtime_wasi::p2::bindings::cli::environment::add_to_linker] as the D type parameter. See HasData for more information about the type parameter’s purpose.

When using this type you can skip the WasiCliView trait, for example.

Examples

use wasmtime::component::{Linker, ResourceTable};
use wasmtime::{Engine, Result, Config};
use wasmtime_wasi::cli::*;

struct MyStoreState {
    table: ResourceTable,
    cli: WasiCliCtx,
}

fn main() -> Result<()> {
    let mut config = Config::new();
    config.async_support(true);
    let engine = Engine::new(&config)?;
    let mut linker = Linker::new(&engine);

    wasmtime_wasi::p2::bindings::cli::environment::add_to_linker::<MyStoreState, WasiCli>(
        &mut linker,
        |state| WasiCliCtxView {
            table: &mut state.table,
            ctx: &mut state.cli,
        },
    )?;
    Ok(())
}

Trait Implementations

impl HasData for WasiCli

type Data<'a> = WasiCliCtxView<'a>

The data associated with this trait implementation, chiefly used as a generic associated type to allow plumbing the 'a lifetime into the definition here.
