Struct Message 

#[non_exhaustive]
pub struct Message<'a> {
    pub topic: &'a str,
    pub payload: &'a [u8],
    pub retain: Option<bool>,
}

A message received from the broker, borrowed from the client’s buffer.

Built with Message::new outside this crate.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

topic: &'a str

Topic name the message was published to.

payload: &'a [u8]

Application payload, possibly empty.

retain: Option<bool>

MQTT retain bit; None when the client does not surface it.
