Struct KeyRotationState 

pub struct KeyRotationState {
    pub generation: u64,
    pub established_at: Instant,
    pub max_lifetime: Duration,
    pub grace_period: Duration,
    pub rotating: bool,
}

Key rotation state for a mesh connection.

Fields

generation: u64

Current key generation number.

established_at: Instant

When the current key was established.

max_lifetime: Duration

Maximum key lifetime before rotation.

grace_period: Duration

Grace period: old key accepted during transition.

rotating: bool

Whether rotation is in progress.

Implementations

impl KeyRotationState

pub fn new(max_lifetime: Duration, grace_period: Duration) -> Self

Create a new key rotation state at generation 0.

pub fn needs_rotation(&self) -> bool

Check if key rotation is needed based on elapsed lifetime.

pub fn begin_rotation(&mut self)

Start key rotation (marks as in-progress).

pub fn complete_rotation(&mut self)

Complete key rotation, advancing to the next generation.

pub fn old_key_valid(&self) -> bool

Check if the old key (previous generation) is still valid. True during active rotation or within the grace period.
