//! Reader for Stata dictionary (`.dct`) files.
//!
//! A `.dct` dictionary describes the schema of a fixed-width or
//! free-format plain-text data file. This module parses the
//! dictionary, then iterates observations from the associated data
//! file. Data may be embedded after the dictionary's closing `}` or
//! live in a separate file; see [`DctSource`](crate::stata::dct::DctSource).
//!
//! Unlike the binary DTA format, DCT files are plain ASCII and never
//! carry `strL` references, so the DCT-domain
//! [`Value`](crate::stata::dct::Value) /
//! [`VariableType`](crate::stata::dct::VariableType) types
//! deliberately diverge from their DTA counterparts.
//!
//! # Line endings
//!
//! Both Unix `\n` and Windows `\r\n` line endings are accepted in
//! both the dictionary file and its associated data file. Classic
//! Mac `\r`-only line endings are not — Stata never emitted them and
//! supporting them would require a different reading strategy. A
//! `\r`-delimited file would be read as a single very long line.
