Struct gear_common::MessageId

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 gstd::msg::id() function. Also, each send and reply functions return a message identifier.
