Per-kind persistence toggles.

None means “do not persist this kind”. Some(depth) means persist at the given depth. Master enabled gates everything; individual kinds can still be Some(_) but produce no writes when enabled = false.

All fields that previously existed as bool now carry Option<PersistDepth>. For backward compatibility:

• Default produces None for every kind (same as all-false before).
• PersistenceConfig::on() sets every field to Some(Compact) — identical behavior to the previous true / all-on path.

Fields

enabled: bool

retention_days: Option<u32>

Sweep window for day files, in days. None = keep every day file forever (default, no behavior change). Some(n) deletes .dat/.idx/ .blob triplets older than today - n on DiskStore open and on UTC day rotation — see crate::series::DiskStore.

Implementations

impl PersistenceConfig

pub fn on() -> Self

Enable persistence for every supported kind at Compact depth.

Produces identical output to the previous on() that set all bools to true. Compact = existing <Kind>Point layout, no behavior change.

pub fn retention_days(self, days: Option<u32>) -> Self

Set the day-file retention window. None disables the sweep (keep everything forever); Some(n) sweeps files older than today - n days on DiskStore open + day rotation.

pub fn trades(self, depth: Option<PersistDepth>) -> Self

pub fn agg_trades(self, depth: Option<PersistDepth>) -> Self

pub fn klines(self, depth: Option<PersistDepth>) -> Self

pub fn tickers(self, depth: Option<PersistDepth>) -> Self

pub fn orderbook_snapshots(self, depth: Option<PersistDepth>) -> Self

pub fn mark_price(self, depth: Option<PersistDepth>) -> Self

pub fn funding_rate(self, depth: Option<PersistDepth>) -> Self

pub fn index_price_kline(self, depth: Option<PersistDepth>) -> Self

pub fn premium_index_kline(self, depth: Option<PersistDepth>) -> Self

pub fn market_warning(self, depth: Option<PersistDepth>) -> Self

pub fn orderbook_l3(self, depth: Option<PersistDepth>) -> Self

pub fn is_enabled_for(&self, kind: &Kind) -> bool

Should kind be persisted given the current config?

pub fn depth_for(&self, kind: &Kind) -> Option<PersistDepth>

The configured depth for kind, or None if persistence is disabled for this kind (either master enabled=false or the kind’s toggle is None).
