Enum RefreshBuffer 

#[non_exhaustive]
pub enum RefreshBuffer {
    Adaptive(Duration),
    Fixed(Duration),
}

Immutable early-refresh policy. Fixed buffers preserve the source’s absolute window.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Adaptive(Duration)

Cap the chosen maximum at 20% of the issued TTL so short leases remain usable.

Fixed(Duration)

An absolute window; zero disables early refresh and a window >= TTL refreshes each call.
