discord/sorted_set_nif

This system is a high-performance SortedSet library implemented in Rust and exposed to Elixir via Native Implemented Functions (NIFs). It provides core set operations such as adding, removing, and indexing elements, along with sorting and list conversion capabilities. The implementation leverages the jemalloc allocator to expose detailed memory allocation information for profiling and monitoring purposes.

The SortedSet library has updated its NIF bridge to align with Rustler 0.22.x, which changes the return tuples from NIF functions to be wrapped in a {:ok, ...} structure (e.g., {:ok, :ok} instead of :ok, and {:ok, {:added, index}} instead of {:ok, :added, index}). This ensures consistent error handling across operations like add, remove, and size. Additionally, the library now exposes jemalloc memory allocation information via a new jemalloc\_allocation\_info function, allowing users to inspect memory usage details reported by the underlying allocator.

The benchmark scripts in the bench directory have been updated to align with the latest Benchee API, switching from the deprecated function-argument formatter syntax to the new module-attribute style for both Console and HTML formatters. Additionally, the construction benchmarks now reference the Discord.SortedSet module instead of the local SortedSet module for proper and shuffled enumerable construction tests.

The native SortedSet implementation has been upgraded to Rustler 0.37, replacing the legacy \rustler\_export\_nifs!\ macro with the declarative \rustler::init!\ macro. This change modernizes the NIF bridge by using \\#\[rustler::nif\]\ attributes for function registration and \\#\[rustler::resource\_impl\]\ for resource management, simplifying the API surface and improving type safety. Additionally, the module now integrates the jemalloc allocator via \jemallocator\ and exposes \jemalloc\_allocation\_info\ for memory profiling, while internal code has been refactored to use explicit \crate::\ paths and idiomatic Rust patterns.

_native/sorted\_set\nif · high confidence

Added tests to verify SortedSet behavior across multiple operations (add, remove, index\_add, index\_remove, size, slice, sorting, to\_list) by updating the test suite to use the new \check all(...)\ syntax required by the updated test framework.

The native NIF dependency on Rustler has been upgraded from version 0.18 to 0.37, requiring a corresponding update to the Elixir project configuration. Additionally, the \jemalloc\_info\ and \jemallocator\ crates have been added to the Rust dependencies, introducing memory allocation instrumentation and a custom allocator, while the project version has been bumped to 2.0.1.
