        Default,
        Manual(usize),
    }

Expand description

The maximum per-worker concurrent TLS connection limit.

All listeners will stop accepting connections when this limit is reached. It can be used to limit the global TLS CPU usage. By default max connections is set to a 256. Takes a string value: Either “default”, or an integer N > 0 e.g. “6”.

## Variants

### `Default`

The default connection limit. See struct docs.

### `Manual(usize)`

A specific connection limit.
