pub struct MessageId(pub [u8; 32]);
Expand description
Message identifier.
Gear allows users and programs to interact with other users and programs via
messages. Each message has its unique 256-bit identifier. The MessageId
struct represents this identifier. One can get the message identifier for
the currently processing message using the msg::id
function. Also, each send and reply functions return a message identifier.
§Examples
use gcore::msg;
#[no_mangle]
extern "C" fn handle() {
let current_message_id = msg::id();
}
