Struct QueueFn 

pub struct QueueFn {
    pub name: &'static str,
    pub sig_hash: u64,
    pub trampoline: fn(ctx: &Context, args: &[u8]) -> Result<Value>,
}

Host-side registry entry for a #[queue_fn] discovered across loaded wasm apps. The worker dispatches by looking up (app_id, name) in the HashMap<(AppId, String), QueueFn> that the runtime maintains.

The trampoline is the per-function shim the attribute macro emits: it deserializes the msgpack args tuple and calls the user function.

Fields

name: &'static str

Canonical name (matches the user function identifier).

sig_hash: u64

Signature hash — xxh3_64 of the canonicalized signature string.

trampoline: fn(ctx: &Context, args: &[u8]) -> Result<Value>

Trampoline: takes &Context + serialized args, returns the user function’s JSON result (or an error).
