Struct nakadion::api::ApiClient

pub struct ApiClient { /* fields omitted */ }

A client to connect to the API of Nakadi.

The actual HTTP client is pluggable via the DispatchHttpRequest trait.

The ApiClient does retries with exponential backoff and jitter except for the following trait methods:

• SubscriptionApi::request_stream
• SubscriptionApi::commit_cursors
• PublishApi::publish_events_batch

on_retry

A closure to be called before a retry. The error which caused the retry and the time until the retry will be made is passed. This closure overrides the current one and will be used for all subsequent clones of this instance. This allows users to give context on the call site.
