ByteArrayMemory

class ByteArrayMemory(limits: MemoryLimits) : Memory

Represents the linear memory in the Wasm program. Can be shared reference b/w the host and the guest.

try-catch is faster than explicit checks and can be optimized by the JVM. Catching generic RuntimeException to keep the method bodies short and easily inlinable.
