Struct NrHostExt 

#[repr(C)]
pub struct NrHostExt {
    pub set_state: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, key: NrStr, value: NrBytes) -> NrStatus,
    pub get_state: unsafe extern "C" fn(host_ctx: *mut c_void, sid: u64, key: NrStr) -> NrVec<u8>,
}

Host extension table for state management. This is an optional extension that does not modify the core ABI.
