//! Pure-Rust core for finance-datagen.
//!
//! This crate is deliberately polars-free: every generator emits Apache
//! Arrow `RecordBatch` values. The Python bindings hand those `RecordBatch`
//! objects to Python via the Arrow C Data Interface (PyCapsule) and Python
//! constructs the polars `DataFrame` on its side. This avoids the
//! polars-Rust / polars-Python ABI mismatch.
