Function execute 

pub fn execute(
    instructions: &[Instr],
    r: &mut RegisterFile,
    _: &mut Pools,
    err_ctx: &ErrorCtx<'_>,
    callsite_registers: &[Vec<u16>],
    dyn_libs: &[DynamicLibFn],
    structs: &[Struct],
    enums: &[EnumType],
    allocated_arg_count: usize,
    allocated_call_depth: usize,
    host_sigs: &[HostFnSig],
    host_dispatch: &[HostDispatch],
    start: usize,
    native: Option<&NativeCode>,
) -> Result<(), RuntimeError>

Runs instructions from start until the program halts.

Errors

Returns the RuntimeError that stopped the program when one no try caught was raised. The registers and pools are left as the error found them.
