1//! Shared typed dataset primitives for Orbital tables and charts.
2//!
3//! This crate provides [`Dataset`], [`DataRecord`], and [`DataValue`] — the
4//! canonical data model shared by `orbital-datatable` and `orbital-charts`.
5//! Because it has no UI or framework dependencies, any crate in the workspace
6//! can depend on it without introducing cycles.
7//!
8//! # Example
9//!
10//! ```rust
11//! use std::collections::HashMap;
12//! use orbital_data::{DataRecord, DataSchema, DataValue, Dataset, FieldDef};
13//!
14//! let schema = DataSchema::new(vec![
15//!     FieldDef::text("name", "Name"),
16//!     FieldDef::text("role", "Role"),
17//! ]);
18//! let record = DataRecord::new(
19//!     "1",
20//!     HashMap::from([
21//!         ("name".into(), DataValue::Text("Ada".into())),
22//!         ("role".into(), DataValue::Text("Admin".into())),
23//!     ]),
24//! );
25//! let dataset = Dataset::from_records(schema, vec![record]);
26//! assert_eq!(dataset.records.len(), 1);
27//! ```
