native-ipc

native-ipc is the public facade for the native-ipc-rs workspace. It re-exports:

• native-ipc-core for pointer-free codecs, checked shared-memory layouts, sequencing, and audited reader/writer bindings; and
• native-ipc-platform for least-authority native mappings, authenticated capability transfer, and owned helper-process lifecycles on Linux, macOS, and Windows.

Supported targets are Linux and Windows on ARM64 or AMD64, and macOS on ARM64: aarch64-unknown-linux-gnu, x86_64-unknown-linux-gnu, aarch64-pc-windows-msvc, x86_64-pc-windows-msvc, and aarch64-apple-darwin. Other OS/architecture combinations fail compilation instead of selecting an unaudited fallback.

The native_ipc::memory module provides one allocation and lifecycle API for the best native object on the current target: sealed memfd on Linux, Mach VM memory entries on macOS, and unnamed sections on Windows. Regions may be fixed or replacement-growable before sharing, can be cleared for reuse, and can be explicitly destroyed with a complete clearing pass.

Payload bytes received through shared memory remain hostile input. Readers copy them into owned storage and recheck bounded metadata, but the library does not claim integrity against a malicious same-sequence writer.

See the repository README, architecture, and threat model for the complete security contract.
