Struct RotationHandle 

pub struct RotationHandle(/* private fields */);

Wrapper for custom or default secret rotation implementations.

Allows pluggable key derivation strategies while maintaining a consistent API.

Implementations

impl RotationHandle

pub fn new(rotation: impl SecretRotation + 'static) -> Self

Create a new rotation handle with a custom implementation.
