Automatically bind bindings in your `wrangler.toml` into a Rust struct
wrangler.toml
[vars]
MY_VAR = "my-variable"
[[kv_namespaces]]
binding = "MY_KV"
id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
lib.rs
use worker::*;
use worker_bindings::bindings;
/* This knows all your bindings in wrangler.toml */
#[bindings]
struct Bindings;
#[event(fetch)]
pub async fn main(req: Request, env: Env, _ctx: worker::Context) -> Result<Response> {
/* load bindings from env */
let b = Bindings::from(&env);
let var: &'static str = b.MY_VAR;
let data = b.MY_KV.get("data").text().await?;
//...
}
#[bindings]
works in a cargo workspace but has a limitation that it fails to resolvewrangler.toml
if more than one members havewrangler.toml
