Streaming Suspend Input Output library for Kotlin Multiplatform.
This is an async IO extension for kotlinx.io based on the async API proposal.

• Supports all Kotlin Multiplatform targets
• AsyncReadOnlyFileSystem interface
• AsyncFileSystem interface
• AsyncCloseable interface
• AsyncRawSource interface
• AsyncRawSink interface
• AsyncSource wrapper for buffering raw async sources
• AwaitPredicate interface for await conditions like exhausted and available
• DiscardingAsyncSink object for voiding data
• RandomAsyncSource object for sourcing an endless pseudo-random byte stream
• AsyncSystemFileSystem global file system instance via the ssio-core module
• AsyncVirtualFileSystem class via the ssio-vfs module
• AsyncNoopFileSystem object via the ssio-noop module

The following matrix illustrates what implementations are used for which target & runtime combination
in the ssio-core implementation:

NOTE: Implementations marked with an asterisk* are used only when the underlying system supports them.

The answer is simple: you shouldn't if you don't need a suspend IO API available in your common source set.
If you do, this library is probably what you're looking for.

First, add the official Maven Central repository to your settings.gradle.kts:

dependencyResolutionManagement {
    repositories {
        mavenCentral()
    }
}

Then add a dependency on the library in your root buildscript:

kotlin {
    sourceSets {
        commonMain {
            dependencies {
                implementation("dev.karmakrafts.ssio:ssio-core:<version>")
            }
        }
    }
}

Or, if you are only using Kotlin/JVM, add it to your top-level dependencies block instead.
