// src/traits/as_i128.rs : `AsI128`
/// Trait defining instance method `as_i128() : i128` that provides a
/// cost-free conversion into `i128`.
///
/// It is expected that the implementing type "is-a" `i128` in a direct
/// manner as well as in a logical manner.
///
/// # Additional Implementations on Foreign Types
///
/// ## Built-in Types
///
/// If the feature `"implement-AsI128-for-built_ins"`
/// is defined (as it is by `"default"`), then this is also implemented
/// for the following type(s):
/// - [`i128`];
