Struct Frame

struct Frame {
    start: usize,
    end: usize,
    arg_cnt: (u16, bool),
}

A function call frame. These mirror the lisp call stack and are used to display backtraces as well as return.

Fields

start: usize

The start of the call frame, as a index from the bottom of the stack (not the top).

end: usize

The maximum size this stack frame can grow.

arg_cnt: (u16, bool)

Number of arguments in this call frame. The first is the count and the second is boolean indicating if the last argument is a cons with the remaining variadic arguments.
