    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())

case class LabelStack(parent: LabelStack, target: Target, arity: Int, pushed: Int) extends Product with Serializable

A stack of labels, each one tracking following information:

  • the parent label
  • its target on break
  • its arity (i.e. the number of return value to pop and return on break)
  • the number of pushed value so far for the current label At top-level, the parent is null and target is 0. No checks need to be performed because the compiler is only called if the program is correct, in which case all breaks target an existing label. The top-level label is a special synthesized one, representing the top-level block of the function body.
