Replaying a merged +//! event log in HLC order is therefore deterministic on every brain, which makes +//! the projection converge field-by-field (last-writer-in-HLC-order wins) without +//! per-field bookkeeping. This generalizes the single-brain `(ts, rowid)` causal +//! order to the multi-brain case. +//! +//! The canonical wire/storage form is `"{wall_ms:013}.{counter:010}.{node}"` — +//! zero-padded so plain string comparison equals causal comparison. 13 digits +//! covers epoch-millis through year 5138; 10 digits covers the full u32 counter +//! range (the counter only grows within a single ms, then resets). The 10-digit +//! width is also wide enough for the v9 migration to backfill a row's `rowid` +//! into the counter slot (`wall = 0`), so old events sort before new ones by a +//! consistent string width. + +use std::sync::{Mutex, OnceLock}; +use std::time::{SystemTime, UNIX_EPOCH}; + +/// A Hybrid Logical Clock timestamp. +#[derive(Debug, Clone, PartialEq, Eq)] +pub struct Hlc { + pub wall_ms: u64, + pub counter: u32, + pub node: String, +} + +impl Hlc { + /// Canonical sortable string: `{wall_ms:013}.{counter:010}.{node}`. + pub fn to_canonical(&self) -> String { + format!("{:013}.{:010}.{}", self.wall_ms, self.counter, self.node) + } + + /// Parse a canonical string back into an `Hlc`.
