Enum ClientError 

#[non_exhaustive]
pub enum ClientError {
    InvalidState,
    UnexpectedPacket,
    ProtocolError,
    PacketIdExhausted,
    QuotaExhausted,
    QoSNotSupported,
    RetainNotAvailable,
    WildcardSubNotAvailable,
    SubIdNotAvailable,
    SharedSubNotAvailable,
}

Errors from the client state machine.

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.

InvalidState

Operation not valid in the current connection state.

UnexpectedPacket

Received a packet type that the server should never send.

ProtocolError

Server violated the protocol.

PacketIdExhausted

No more packet identifiers available (all 65 535 in use).

QuotaExhausted

Send quota exhausted (Receive Maximum reached).

QoSNotSupported

QoS level exceeds the server’s Maximum QoS capability.

RetainNotAvailable

Server declared Retain Available = false.

WildcardSubNotAvailable

Server declared Wildcard Subscription Available = false.

SubIdNotAvailable

Server declared Subscription Identifiers Available = false.

SharedSubNotAvailable

Server declared Shared Subscription Available = false.

Trait Implementations

impl Clone for ClientError

fn clone(&self) -> ClientError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ClientError

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

Formats the value using the given formatter.

impl PartialEq for ClientError

fn eq(&self, other: &ClientError) -> 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.
