Enum SubReasonCode

#[non_exhaustive]pub enum SubReasonCode {
    UnspecifiedError,
    ImplementationSpecificError,

    TopicFilterInvalid,
    PacketIdentifierInUse,
    QuotaExceeded,
    SharedSubscriptionsNotSupported,

}

Expand description

Reason a subscription was rejected by the broker (the failure half of a SUBACK reason code — Success is a SubscriptionGrant, not a loss).

#[non_exhaustive]: the MQTT 5 reason-code registry may grow, and the v4 mapping only distinguishes success from a single 0x80 failure.

Variants (Non-exhaustive)§

This enum is marked as 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.

UnspecifiedError

Unspecified error (0x80); the only failure v4 can report.

ImplementationSpecificError

The subscription was not accepted for an implementation-specific reason.

NotAuthorized

The client is not authorized to make this subscription.

TopicFilterInvalid

The topic filter is correctly formed but not accepted by this broker.

PacketIdentifierInUse

The packet identifier is already in use.

QuotaExceeded

An implementation or administrative quota was exceeded.

SharedSubscriptionsNotSupported

The broker does not support shared subscriptions.

SubscriptionIdentifiersNotSupported

The broker does not support subscription identifiers.

WildcardSubscriptionsNotSupported

The broker does not support wildcard subscriptions.
