1//! This crate offers a replacement for `serde-json`'s `Value` type, which is
2//! significantly more memory efficient.
3//!
4//! As a ballpark figure, it will typically use half as much memory as
5//! `serde-json` when deserializing a value and the memory footprint of cloning
6//! a value is more than 7x smaller.
7//!
8//! The primary type exposed by this crate is the [`IValue`] type. It is guaranteed
9//! to be pointer-sized and has a niche (so `Option<IValue>` is also guaranteed
10//! to be pointer-sized).
11//!
12//! Cargo features:
13//!
14//! - `ctor`
15//!   A global string cache is used when interning strings. This cache is normally
16//!   initialized lazily on first use. Enabling the `ctor` feature will cause it
17//!   to be eagerly initialized on startup.
18//!   There is no performance benefit to this, but it can help avoid false positives
19//!   from tools like `mockalloc` which try to detect memory leaks during tests.
