1//! Writer and reader configuration types.
2//!
3//! This module defines the configuration objects that control how a
4//! `dryice` file is written. The primary user-facing construction path
5//! is the builder on [`DryIceWriter`](crate::DryIceWriter). Sequence,
6//! quality, and name codecs are selected via type parameters on the
7//! builder, not through this config.
