Enum Command 

#[non_exhaustive]
pub enum Command {
    #[non_exhaustive]
    Subscribe {
        filters: Vec<(String, QoS)>,
    },
    #[non_exhaustive]
    Unsubscribe {
        filters: Vec<String>,
    },
    #[non_exhaustive]
    Publish {
        topic: String,
        payload: Vec<u8>,
        qos: QoS,
        retain: bool,
    },
}

Available on crate feature alloc only.

Work for the MQTT client.

Each variant is #[non_exhaustive]: match it with .., and build it with Command::subscribe, Command::unsubscribe or Command::publish outside this crate.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

#[non_exhaustive]

Subscribe

Subscribe to every filter in one SUBSCRIBE packet.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

filters: Vec<(String, QoS)>

Topic filters with their requested maximum QoS.

#[non_exhaustive]

Unsubscribe

Unsubscribe from every filter in one UNSUBSCRIBE packet.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

filters: Vec<String>

Topic filters to remove.

#[non_exhaustive]

Publish

Publish one message.

Fields

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.

topic: String

Topic name.

payload: Vec<u8>

Application payload.

qos: QoS

QoS to publish with.

retain: bool

MQTT retain flag.
