VM.CallSnapshot

Synopsis

data CallSnapshot = CallSnapshot {
- callbackIndex :: Int
- vStackIndex :: Int
- vEnv :: Vector VMValue
}

Documentation

data CallSnapshot Source #

Represents a single frame in the call stack.

@details A CallSnapshot is pushed onto the call stack whenever a function is called. It acts as a checkpoint, storing the context of the caller so the VM can restore it when the called function returns.

Constructors

CallSnapshot

Fields

callbackIndex :: Int
The address (ByteString index) where execution should resume after the current function returns.
vStackIndex :: Int
The value of the Frame Pointer before the call. This is essential to restore the caller's view of its local variables.
vEnv :: Vector VMValue
The environment captured by the closure being executed. Allows the function to access variables defined outside its body but available at definition time.
