    This package contains all the classes and types related to running WebAssembly modules.

    This package contains all the classes and types related to running WebAssembly modules.

    The entry point for almost all users will be Engine. A typical use of the engine is:

    import swam._
    import text._
    import runtime._
    import exports._
    
    import cats.implicits._
    import cats.effect._
    
    import java.nio.file.Paths
    
    val tcompiler = Compiler[IO]
    val engine = Engine[IO]
    
    for {
      tcompiler <- tcompiler
      engine <- engine
      mod <- engine.compile(/* source of the module */)
      inst <- mod.newInstance()
      f <- inst.exports.function1[Int, Int]("f")
      res <- f(43)
    } yield res
    
    println(res.unsafeRunSync())

    Transforms a WebAssembly program into another one.

    Transforms a WebAssembly program into another one. Tree traversal is performed in bottom-up order, with a _preparation_ phase for recursive instructions to upgrade the context before inspecting children.

    Every instruction has a default noop transform method, as well as a instruction categories (see group Category for instructions).

    To implement your own transformation, you can override the methods that need specific handling.

    A Transformer is a cats.Semigroup, two transformers can be merged into one, based on the approach presented in Miniphases: Compilation using Modular and Efficient Tree Transformations. When merged, two transformers are fused, making it possible to perform both transformations in one tree traversal only. Make sure your transformations respect the criteria defined in section 6 of the Miniphase paper to fuse them, otherwise, behavior of the result won't be the expected one. If not, transformations cannot be fused, and must be chained one after the other and perform two tree traversals.

  4. class Traverser[F[_], Res] extends AnyRef

    Traverses a WebAssembly program and computes some result.

    Traverses a WebAssembly program and computes some result. Tree traversal is performed in bottom-up order, with a _preparation_ phase for recursive instructions to upgrade the context before inspecting children.

    Every instruction has a default noop traverse method, as well as a instruction categories (see group Category for instructions).
