    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 FunctionContext(labels: LabelStack, errata: List[(Target, (Int) => Unit)], offsets: Map[Target, Int], offset: Int, nxt: Int) extends Product with Serializable

Compilation context used when compiling instructions for a function. The label stack represents the static trace of the program so far in terms of stack modifications, the errata registers the label to fix later, and the jump label offsets. This allows to compile code in one pass even with forward jumps.

The errata lists how to set correct offset for target labels.

The offsets maps label names to their offset.

Once all code has been generated, the placeholders pointed by the errata map are replaced with real offsets from the offsets map.
