Struct HybridClock 

pub struct HybridClock { /* private fields */ }

A Hybrid Logical Clock instance for a single node.

Call now to generate timestamps for local events. Call receive when processing a remote timestamp.

Implementations

impl HybridClock

pub fn new(node_id: u16) -> Self

Create a new clock for the given node.

On std targets, uses SystemTime for physical time. On no_std targets, use with_time_source.

pub fn with_time_source(node_id: u16, time_fn: fn() -> u64) -> Self

Create a clock with a custom physical time source. The function should return milliseconds (monotonic if possible).

pub fn now(&mut self) -> HybridTimestamp

Generate a timestamp for a local event.

Guarantees monotonically increasing timestamps even if the physical clock goes backward.

pub fn receive(&mut self, remote: &HybridTimestamp) -> HybridTimestamp

Update the clock upon receiving a remote timestamp.

Returns a new timestamp that is strictly greater than both the local clock and the received timestamp.

pub fn node_id(&self) -> u16

Get the node ID of this clock.

pub fn last_timestamp(&self) -> HybridTimestamp

Get the last generated timestamp.
