2//! Architecture system uses default Rust supported platforms and architectures.
3//!
4//! Alignment values are not randomly chosen or incorporated directly.
5//! Values are considered and incorporated inside with the mindset of preventing false sharing
6//! or creating less warp points in exclusive caching.
7//!
8//! Please head to the documentation of [Cuneiform](https://docs.rs/cuneiform/0.1.0/src/cuneiform/slabs.rs.html#5) for more info.

15/// Applies padding based on the architecture detected by cuneiform.
16/// This struct allows us to have padding on only wrapped field.
17///
18/// Cache line size is determined by a few steps:
19/// * It checks the current compiler architecture is already known by cuneiform.
20///     * If known it applies that value as alignment for the field.
21/// * If it is still not detected then fallback padding will be used.
