1. Overview. In this tutorial, we will talk about Kotlin Contracts. Their syntax is not stable yet, but the binary implementation is, and Kotlin stdlib itself is already putting them to use.

Kotlin Contract — What it fixes. In this example, we have a function createOnce that we know, runs the runFunction exactly once. We use this function in the getKotlinVersion and try to initialize a val...

Kotlin Contracts are a new experimental feature introduced in Kotlin 1.3 . The main purpose of contracts is to help the Kotlin compiler with complicated code analysis in cases where the developer...

(Kotlin) Contracts allow a function to explicitly describe its behavior in a way which is understood by the compiler. This means that we have the capability to explicitly tells the compiler that we want...

Kotlin - Why do compiler contracts only allow references to function parameters. When writing validation function, often times these validation functions check for nullability.

Kotlin contracts are exactly solving this kind of problem. With a contract, you can actually provide knowledge about a function behavior to the compiler in order to help it perform a more complete...

This post explores contracts which are introduced in Kotlin 1.3 as an experimental feature. The Kotlin smartcast feature allows to write cleaner code and reduce boilerplate.

Kotlin Contracts. 27 September 2018. The Kotlin type system is fairly flexible but there are a few corner cases where the compiler enforces rules which can be a little restrictive.

contract-call is never evaluated as a Kotlin expression (be it compile-time or runtime)! Therefore, exact implementations of classes and methods of DSL in stdlib do not matter (in fact...

Currently the Kotlin compiler does not verify contracts, so it's a programmer's responsibility to write correct and sound contracts. @UseExperimental(ExperimentalContracts::class) fun FirebaseUser...

Contracts were introduced in Kotlin 1.3 and they can be used to express programmer's intents in situations where compiler may have some doubts and refuse to do its job until there is no ambiguity.

Kotlin is introducing Contracts in the upcoming 1.3 release (currently m2) in which we Starting with Kotlin 1.3, we can start defining contracts for our functions. In the example above, we know from the...

Contracts are a new experimental feature added to Kotlin's type system to describe additional guarantees on top of those represented through a function's signature.

In the world of Kotlin, contracts represent a deal between the developer and the compiler. As a developer you can share insight of your code with the compiler and it can use this extra info for better...

Kotlin (/ˈkɒtlɪn/) is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin's standard library depends on the Java Class Library, but type inference allows its syntax to be more concise.
