Struct StagedRollout 

pub struct StagedRollout { /* private fields */ }

Staged rollout configuration and delay calculation.

Implementations

impl StagedRollout

pub fn new(node_id: &[u8], max_delay_hours: u64) -> Self

Create a new staged rollout calculator.

Arguments

• node_id - The node’s unique identifier (typically a public key)
• max_delay_hours - Maximum rollout window (default: 24 hours)

pub fn calculate_delay(&self) -> Duration

Calculate the delay before this node should apply an upgrade.

The delay is deterministically derived from the node ID, ensuring:

• Each node gets a consistent delay on every check
• Nodes are evenly distributed across the rollout window
• The delay is reproducible (same node ID = same delay)

pub fn max_delay_hours(&self) -> u64

Get the maximum rollout window in hours.

pub fn is_enabled(&self) -> bool

Check if staged rollout is enabled (max_delay_hours > 0).

pub fn calculate_delay_for_version(&self, version: &Version) -> Duration

Calculate the delay for a specific version upgrade.

This includes the version in the hash to ensure different versions get different delays for the same node (useful for critical updates that should be spread differently).
