Trait WasiHttpView 

pub trait WasiHttpView {
    // Required method
    fn http(&mut self) -> WasiHttpCtxView<'_>;
}

Available on crate feature p2 only.

A trait used to project state that this crate needs to implement wasi:http from the self type.

This trait is used in add_to_linker_sync and add_to_linker_async for example as a bound on T in Store<T>. This is used to access data from T, the data within a Store, an instance of WasiHttpCtxView. The WasiHttpCtxView contains contextual information such as the ResourceTable for the store, HTTP context info in WasiHttpCtx, and any hooks via WasiHttpHooks if the embedder desires.

Example

use wasmtime::component::ResourceTable;
use wasmtime_wasi_http::WasiHttpCtx;
use wasmtime_wasi_http::p2::{WasiHttpView, WasiHttpCtxView};

struct MyState {
    http_ctx: WasiHttpCtx,
    table: ResourceTable,
}

impl WasiHttpView for MyState {
    fn http(&mut self) -> WasiHttpCtxView<'_> {
        WasiHttpCtxView {
            ctx: &mut self.http_ctx,
            table: &mut self.table,
            hooks: Default::default(),
        }
    }
}

Required Methods

fn http(&mut self) -> WasiHttpCtxView<'_>

Returns an instance of WasiHttpCtxView projected out of self.
