Enum ServerConnectError 

pub enum ServerConnectError {
    UnacceptableProtocolVersion,
    IdentifierRejected,
    ServerUnavailable,
    BadUserNameOrPassword,
    NotAuthorized,
    Unknown(u8),
    ProtocolError,
}

An enumeration of all the possible error codes returned by the broker in response to the client’s CONNECT packet.

Variants

UnacceptableProtocolVersion

The broker refused our request for the MQTT v3 protocol.

IdentifierRejected

The identifier specified by the developer has been was not allowed by the broker.

ServerUnavailable

The broker responded but is currently unavailable.

BadUserNameOrPassword

The username and/or password data is malformed.

NotAuthorized

ProtocolError

This is not an official MQTT v3 error and is specific to this library. It usually means that the server the developer is trying to connect to is probably not an MQTT broker.

Trait Implementations

impl Clone for ServerConnectError

fn clone(&self) -> ServerConnectError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ServerConnectError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ServerConnectError

fn eq(&self, other: &ServerConnectError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
