1//! Ergonomic `From<primitive>` conversions into [`Value`].
2//!
3//! These fluent-API conversions previously lived in
4//! `reddb-server`'s `storage::unified::devx::conversions`. Once [`Value`]
5//! moved to this keystone crate (ADR 0052) the orphan rule required them to
6//! live with the type they construct: both sides — `Value` and the std
7//! primitive — must have a local anchor, and that anchor is `Value` here.
8//! The bodies are byte-faithful relocations; behaviour is unchanged.
