Function holochain_wasmer_host::guest::call

pub fn call<I, O>(
    store_mut: &mut StoreMut<'_>,
    instance: Arc<Instance>,
    f: &str,
    input: I
) -> Result<O, RuntimeError>
where
    I: Serialize + Debug,
    O: DeserializeOwned + Debug,

Host calling guest for the function named call with the given payload in a vector of bytes result is either a vector of bytes from the guest found at the location of the returned guest allocation pointer or a RuntimeError built from a WasmError. The reason that this takes a separate store and instance is that the host does not neccessarily have access to an InstanceWithStore, such as the case when the guest is called from within a host function call.
