}
Expand description

A client context that supports rewriting broker addresses.

Fields§

§inner: C§overrides: HashMap<BrokerAddr, BrokerAddr>§drop_tokens: Vec<Box<dyn Any + Send + Sync>>

Opaque tokens to cleanup resources associated with overrides.

Implementations§

Constructs a new context that wraps inner.

Adds a broker rewrite rule.

Connections to the specified broker will be rewritten to connect to rewrite_host and rewrite_port instead. If rewrite_port is omitted, only the host is rewritten.

The same as add_broker_rewrite, but holds onto a token that may perform some shutdown on drop.

Returns a reference to the wrapped context.

Implements the default rebalancing strategy and calls the pre_rebalance and post_rebalance methods. If this method is overridden, it will be responsibility of the user to call them if needed.
Pre-rebalance callback. This method will run before the rebalance and should terminate its execution quickly.
Post-rebalance callback. This method will run after the rebalance and should terminate its execution quickly.
Post commit callback. This method will run after a group of offsets was committed to the offset store.
Returns the minimum interval at which to poll the main queue, which services the logging, stats, and error callbacks. Read more
A DeliveryOpaque is a user-defined structure that will be passed to the producer when producing a message, and returned to the delivery method once the message has been delivered, or failed to.
This method will be called once the message has been delivered (or failed to). The DeliveryOpaque will be the one provided by the user when calling send.
