## Intended use-case
Noleader is not built for distributed consensus, or fast re-election produces. It take upwards to a minute to get reelected, state is the users responsibility to handle.

Noleader is pretty much just a distributed lock, intended for use-cases where the use wants to only have a single node scheduling work etc.

## API Overview
## Examples
* **`Leader::new(bucket: &str, key: &str, client: async_nats::Client) -> Leader`**
Create a new election participant.
* **`create_bucket(&self) -> anyhow::Result<()>`**
Ensures the KV bucket exists (no-op if already created).
* **`start(&self, token: CancellationToken) -> anyhow::Result<()>`**
Begins the background leader-election loop; renews TTL on success or retries on failure.
* **`do_while_leader<F, Fut>(&self, f: F) -> anyhow::Result<()>`**
Runs your closure as long as you hold leadership; cancels immediately on loss.
* **`leader_id(&self) -> Uuid`**
Returns your unique candidate ID.
* **`is_leader(&self) -> Status`**
Returns `Status::Leader` or `Status::Candidate`, taking shutdown into account.
See the examples folder in ./crates/noleader/examples
### Types
## Architecture
Noleader uses a simple election stealing
```rust
pub enum Status {
Leader,
Candidate,
}
```
