Function compose_rust_host_dispatch_event 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn compose_rust_host_dispatch_event(
    event: *const u8,
    len: u32,
    out: *mut MutationBatch,
) -> i32

Dispatches one encoded event synchronously and returns its diff batch.

Safety

event must address len readable bytes and out must be writable.
