Kotlin Libraries

The Kotlin bindings expose Media over QUIC to Android apps and JVM-based services. Built on the same Rust core (moq-ffi) as the Python and Swift packages, wrapped with idiomatic Flow and coroutines.

Packages

Two Kotlin Multiplatform artifacts, each publishing JVM and Android variants under one coordinate.

dev.moq:moq

The ergonomic wrapper. Pure Kotlin layered on dev.moq:moq-ffi: a Moq.connect(...) facade, Flow-based async sequences with structured cancellation, and clean dev.moq typealiases for the FFI types. Versioned independently of the crate. Most consumers want this.

dev.moq:moq-ffi

The raw UniFFI bindings (uniffi.moq.*) plus the native binaries (JNI on Android, JNA on desktop JVM: Linux, macOS, Windows; arm64-v8a, armeabi-v7a, x86_64). Auto-released on every moq-ffi-v* tag, so its version tracks the crate. Depend on it directly only if you want the FFI surface without the wrapper.

Installation

// build.gradle.kts
dependencies {
    implementation("dev.moq:moq:0.4.3")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.9.0")
}

The wrapper depends on dev.moq:moq-ffi:[0.3,0.4), so Gradle pulls the newest bindings patch (with its bundled native binaries) automatically; no extra setup is needed on the consumer side. The wrapper publishes via release-kt-lib.yml and the bindings via release-kt-ffi.yml.

Quickstart

import dev.moq.*
import kotlinx.coroutines.flow.collect

Moq.connect("https://relay.example.com").use { moq ->
    moq.announcements("demos/").collect { announcement ->
        println("got broadcast ${announcement.path()}")

        announcement.broadcast().subscribeCatalog().updates().collect { catalog ->
            println("catalog: $catalog")
        }
    }
}

Moq.connect wires an internal origin for publish + subscribe and returns a Moq you can use {}. Cancelling the surrounding coroutine scope propagates through to the native consumer's cancel() via the wrapper's onCompletion hook.
