Crate chronix_core 

chronix-core

Core data model, types, errors, and configuration for the Chronix time-series database. This crate provides the foundational types that all other Chronix crates depend on.

Overview

• Data model: FieldValue, SeriesKey, Point — the fundamental units of time-series data.
• Exact decimals: Decimal — mantissa × 10⁻ˢᶜᵃˡᵉ for the one class of series whose value is a legal quantity: metering, billing and settlement. See decimal for why a f64 cannot carry those.
• Schema: MeasurementSchema, SchemaRegistry — schema-on-write with additive evolution.
• Calendar buckets: TimeBucket — the one answer to “what is a day”, shared by SQL’s time_bucket(), a rollup tier and the native downsample() plan, so the three cannot disagree. See timebucket.
• Errors: ChronixError — crate-level and top-level error hierarchy.
• Configuration: ChronixConfig, WalConfig — full database configuration with builder pattern.
