//! Core type definitions for every decimal width and their scale aliases.
//!
//! Each width is a `#[repr(transparent)]` newtype around an integer
//! storage of the matching size. The stored integer equals
//! `actual_value * 10^SCALE`. Widths:
//!
//! `MAX_SCALE = name - 1` for every width (the scale cap guaranteeing
//! at least one integer digit of headroom at every legal `SCALE`):
//!
//! | Type | Storage | `MAX_SCALE` |
//! |------|---------|-------------|
//! | [`D18<SCALE>`] | `i64`             | 17  |
//! | [`D38<SCALE>`] | `i128`            | 37  |
//! | [`D76<SCALE>`] | `crate::int::types::Int<4>` | 75 |
//! | [`D153<SCALE>`] | `crate::int::types::Int<8>` | 152 |
//! | [`D307<SCALE>`] | `crate::int::types::Int<16>` | 306 |
//!
//! The `#[repr(transparent)]` annotation is load-bearing: it guarantees
//! the same ABI as the underlying integer, so `from_bits` / `to_bits`
//! round-trips are exact and the types are safe to embed in C-ABI
//! plugin payloads when the underlying integer matches a primitive.

// `RoundingMode`). Both delegate straight to the int const base, so they

// single-tier hops kept for source compatibility), and a second inherent
// method of the same name on the aliased `D<Int<N>, SCALE>` would be a
