pub struct MessageId(/* private fields */);
Expand description
Message identifier.
Gear allows users and program interactions via messages.
Each message has its own unique 256-bit id. This id is represented
via the MessageId
struct. The message identifier can be obtained for the
currently processed message using the msg::id
function.
Also, each send and reply functions return a message identifier.
