write_json_emitter_alt_c.rs

1//! Source: `Analysis/include/Luau/JsonEmitter.h` (lines 236-245, hand-ported)
2//!
3//! C++ template:
4//! ```cpp
5//! template<typename T>
6//! void write(JsonEmitter& emitter, const std::unordered_map<std::string, T>& map)
7//! {
8//!     ObjectEmitter o = emitter.writeObject();
9//!     for (const auto& [k, v] : map)
10//!         o.writePair(k, v);
11//!     o.finish();
12//! }
13//! ```
14//!
15//! DcrLogger stores these maps as `DenseHashMap` / `std::unordered_map` (ported
16//! to `std::collections::HashMap`); both string-keyed forms write as objects
17//! keyed by the (string) key, exactly as the C++ unordered_map overload.
