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

dev.moq:moq

A single Kotlin Multiplatform module that publishes both JVM and Android variants under one coordinate. Consumers add dev.moq:moq:VERSION and Gradle metadata resolution picks the right artifact for their target.

Features:

• Android (arm64-v8a, armeabi-v7a, x86_64) and desktop JVM (Linux, macOS, Windows)
• Flow-based async sequences with structured cancellation
• Native binaries bundled via JNI (Android) / JNA (desktop JVM)

Installation

// build.gradle.kts
dependencies {
    implementation("dev.moq:moq:0.2.0")
    implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.9.0")
}

Published to Maven Central via release-kt.yml. Native binaries for all supported targets are bundled in the artifact, so no extra setup is required on the consumer side.

Quickstart

import dev.moq.*
import kotlinx.coroutines.flow.collect
import uniffi.moq.MoqClient
import uniffi.moq.MoqOriginProducer

// Wire an origin as both publish source and consume sink. Set just one
// side for a subscribe-only or publish-only client.
val origin = MoqOriginProducer()
val client = MoqClient()
client.setPublish(origin)
client.setConsume(origin)

val session = client.connect("https://relay.example.com")

origin.use {
    val consumer = origin.consume()
    val announced = consumer.announced("demos/")
    announced.announcements().collect { announcement ->
        println("got broadcast ${announcement.path()}")

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

session.shutdown()

Cancelling the surrounding coroutine scope propagates through to the native consumer's cancel() via the wrapper's onCompletion hook.
