AMT Protocol Library

Rust implementation of the Automatic Multicast Tunneling (AMT) protocol (RFC 7450).

Multi-platform library with FFI, WASM, and JNI targets.

Building

FFI (for CGO/C/C++)

make ffi
# Output: target/release/libamt_protocol.{so,a}

Install to system

make install
# Or with custom prefix:
make install INSTALL_PREFIX=/opt/amt

WASM (for web browsers)

make install-wasm-deps  # one-time
make wasm
# Output: dist/wasm/

Android JNI

make install-android-deps  # one-time
export ANDROID_NDK_HOME=/path/to/ndk
make jni
# Output: dist/android/

Usage with Go (CGO)

After installing the library:

import "github.com/blockcast/go-amt"

Build with CGO enabled:

CGO_ENABLED=1 go build

Features

• ffi: C FFI bindings (staticlib + cdylib)
• wasm: WebAssembly via wasm-bindgen
• jni: Android JNI bindings
• native: tokio-based async runtime + amt-verify CLI

CLI: amt-verify

A native CLI for end-to-end AMT tunnel verification (one-shot or --watch), built when this crate is compiled with --features native:

cargo build --release --no-default-features --features native --bin amt-verify

See docs/runbook-staging-e2e.md for the staging verification procedure.
