Documentation

rs_facetime

Unstable — still in development. APIs and behavior may change without notice.

FaceTime Audio private API bridge for macOS (separate from rs_imessage).

Status

Piece State
Rust IPC client + FaceTime.app launcher private-api feature
rs-facetime-bridge-helper.dylib ./scripts/build-bridge.sh → lib/

Protocol: v2 file-queue under ~/Library/Containers/com.apple.FaceTime/Data/.rs-facetime-rpc/.

Requirements

  • macOS 14+
  • FaceTime.app
  • SIP disabled for dylib injection
  • Helper dylib built for your OS/arch (see matrix below)

Library

rs_facetime = { version = "0.1", default-features = false, features = ["private-api"] }

use rs_facetime::private_api::BridgeClient;

let bridge = BridgeClient::connect()?;
bridge.ping()?;

RS_FACETIME_BRIDGE_DYLIB overrides dylib search path.
