Function wasmtime_wasi_http::add_to_linker_async

pub fn add_to_linker_async<T>(l: &mut Linker<T>) -> Result<()>
where
    T: WasiHttpView + WasiView,

Add all of the wasi:http/proxy world’s interfaces to a wasmtime::component::Linker.

This function will add the async variant of all interfaces into the Linker provided. By async this means that this function is only compatible with Config::async_support(true). For embeddings with async support disabled see add_to_linker_sync instead.

Example

use wasmtime::{Engine, Result, Config};
use wasmtime::component::{ResourceTable, Linker};
use wasmtime_wasi::{WasiCtx, WasiView};
use wasmtime_wasi_http::{WasiHttpCtx, WasiHttpView};

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

    let mut linker = Linker::<MyState>::new(&engine);
    wasmtime_wasi_http::add_to_linker_async(&mut linker)?;
    // ... add any further functionality to `linker` if desired ...

    Ok(())
