Function retry_api_call 

pub async fn retry_api_call<T, F, Fut>(
    operation: F,
    operation_name: &str,
) -> Result<T>
where
    F: FnMut() -> Fut,
    Fut: Future<Output = Result<T, Error>>,

Retry a Kubernetes API call with exponential backoff.

Automatically retries on transient errors (HTTP 429, 5xx) and fails immediately on permanent errors (4xx client errors except 429).

Arguments

• operation - Async function that performs the API call
• operation_name - Human-readable name for logging (e.g., “get cluster”)

Returns

Result of the API call after retries

Errors

Returns error if:

• Non-retryable error encountered (4xx client error)
• Max elapsed time exceeded (5 minutes)
• All retries exhausted

Example

use kube::{Api, Client};
use bindy::crd::Bind9Cluster;
use bindy::reconcilers::retry::retry_api_call;

let client = Client::try_default().await?;
let api: Api<Bind9Cluster> = Api::namespaced(client, "default");

let cluster = retry_api_call(
    || async { api.get("my-cluster").await.map_err(Into::into) },
    "get cluster my-cluster"
).await?;
