orbital-data 0.1.1

//! Shared typed dataset primitives for Orbital tables and charts.
//!
//! This crate provides [`Dataset`], [`DataRecord`], and [`DataValue`] — the
//! canonical data model shared by `orbital-datatable` and `orbital-charts`.
//! Because it has no UI or framework dependencies, any crate in the workspace
//! can depend on it without introducing cycles.
//!
//! # Example
//!
//! ```rust
//! use std::collections::HashMap;
//! use orbital_data::{DataRecord, DataSchema, DataValue, Dataset, FieldDef};
//!
//! let schema = DataSchema::new(vec![
//!     FieldDef::text("name", "Name"),
//!     FieldDef::text("role", "Role"),
//! ]);
//! let record = DataRecord::new(
//!     "1",
//!     HashMap::from([
//!         ("name".into(), DataValue::Text("Ada".into())),
//!         ("role".into(), DataValue::Text("Admin".into())),
//!     ]),
//! );
//! let dataset = Dataset::from_records(schema, vec![record]);
//! assert_eq!(dataset.records.len(), 1);
//! ```
